Solipskier is a game that's a little like Line Rider, in that you draw the terrain your character will travel on. Except your character is on skis, and can do wicked jumps and go 200kph.

Medals (7 for 110pts):
Nice Jump (5) - Get 100k points in a single high jump.

Bronze Medal In Awesomeness (10) - Achieve 1m points in a single run.

Where'd All My Tunes Go At?! (10) - Go fast enough to lose your headphones to the wind. Fast enough is 70kph.

Wicked Tricks (10) - Achieve a 50x multi.

Awesome Combo! (25) - Achieve 100x multi.

Gold Medal In Awesomeness (25) - Achieve 50m points in a single run. As of the time of this writing, it actually requires 100m points in a single run, verified by many in the Newgrounds Medal Games - Tips and Tricks thread.

Sick Air! (25) - Get 1m points in a single high jump. More on this later.

Gameplay:
The premise of this game is simple: draw the snow on which your skier will travel. When your skier is in the air and you're not drawing snow, he will do tricks. Hit gates to increase your speed and multiplier, hit them in midair to do so for a larger effect, and jump off the screen and over gates while off screen for a nice big bonus. All of the medals will come to you with enough playtime, which is undoubtedly why they're not worth that much.

In-Game Tips:
Running Poorly? Try disabling some of the graphics (gfx) options in the options menu to the left. Hopefully that will fix you up just fine.

Rainbow Bonus Keep your multiplier up by doing tricks in the air. While airborne, stop painting snow and you'll do tricks.

Buzz The Tower You get a big speed boost for passing through green gates while in mid-air. It also adds two extra on your multiplier.

Reach The Stars By jumping high in the sky you can earn extra points. The more gates you pass on your jump, the higher your score.

Perfect Tunnel Try your best to hit all the gates on a tunnel to rack huge bonus points. It helps to keep your eyes on the arrow.

Picking Up Speed Draw long downslopes with small upslopes and hit gates. Also, try to keep your cursor on the right side of the screen.

Mind The Gap You can't draw over jumps so make sure to time it right to clear the gap safely. The danger signs will hint when it's coming.

Suicide Hurts You Try your best not to kill yourself. If you run int oa vertical drift that you painted, or draw over the top of Solipskier, you'll die.

Avoid The Reds The "X" gates will kill Solipskier immediately, so beware. Use the long vertical line on the icon as a guide so you avoid it.

The Scoring Table High jumps can get you some serious points, but you have to travel high. Try to draw a steep slope to send Solipskier flying.

Where My Tunes? Sometimes Solipskier goes so fast he loses his headphones. Don't be alarmed, just listen to the wind and ride hard!

Gameplay Tips:
First of all, if you're skiing slowly you can draw a quick up and down, and you'll rapidly speed up to about 25-30kph. This can be helpful when you want to get your speed up, and is a quick way to start getting places at the beginning of your game.

There are two basic ways to play the game: jumps or skiing. Jumps involves getting a nice juicy multiplier, say about 80x, and then launching yourself into the air over and over until you lose it. As long as you don't miss a gate when you land, and you don't crash, you can keep building your multiplier this way as you jump over gates, and eventually you may get the 1m jump medal. Skiing takes more practice, and is the higher scoring gameplay method. Rather than jumping, you stay on the screen as much as possible, and focus on hitting gates and tunnels. You will always get more points for jumping through gates than jumping over them, without exception, so if you're going for a big score you'll definitely want to play by skiing. Like this person, who is not me:

Some things I've learned from my 100m attempts (current best 188m): Once you're going fast enough, don't worry about jumping through gates; skiing through them is enough, and can be done with more control. Don't jump if you can avoid it, and learn how to time small bounds at high speed in order to more dynamically claim gates that are far apart. When faced with red gates, jump past them rather than skiing past them, as being in the air seems to prolong your multiplier. And never underestimate the power of a perfect tunnel.

What's In This Game, Anyway?
Tunnels are important. Each one has 40 gates, and that tip up there is serious when it says you'll get huge bonus points for a perfect tunnel. The bonus for a perfect tunnel is dependant on both your multiplier and your speed, and I've gotten one as high as 19m. That's not even close to the highest I've seen someone else do, which is 97m, more than the 73m in the video you just passed at only a marginally better multiplier. You don't have to hit each gate on snow; just like regular gates you can be in the air when you go through them. However, when you get up to a very high speed it will quickly become impractical to try to keep up with the more windy tunnels, and you'll be better off picking and choosing when to follow the tunnel, and when to let it get away in order to avoid jumping over it; better to miss 20 gates than 35 and part of the next tunnel.

Speed is cool, but it takes a lot of practice to control Solipskier over 100kph. If you find you're having trouble controlling him, rather than toss him up in the air you should just draw your snow right at the top of the screen and miss 2 or 3 gates until you slow down to a manageable speed. This will keep you in control, and you'll lose your speed without the risk of coming down in the middle of a jump where you can't draw any snow to land on.

Jumps are an irritant, but they can be used to your advantage. With a bit of practice, you'll be able to use a jump to get your Solipskier into position for the next gate or tunnel without the risk of missing a gate along the way. One thing to look out for is consecutive jumps, because your landing area from the first one may be within the second one where you can't draw. It may be best to take a high jump in such cases and just hope for the best. However, once you get up to a sufficient speed you'll be able to just hold a horizontal path with your Solipskier, and he'll skip right past the jump for you. Just make sure that when you try this you're not in danger of losing your speed bonus, or you'll crash right into your snow and die.

Buzzing the tower doesn't require you to have any upward momentum, it just requires you to be in the air. A really simple trick for gaining speed and a multiplier quickly at the start of the game, or any time your speed and multiplier drop right down, is to ski up to the top of a gate and stop drawing your snow just before you get to it, and then draw some snow below the gate on the other side. Solipskier will pass through the gate, pick up speed, and that will be all you need in order to get yourself going. As you continue to play, with a bit of practice you'll be able to time drawing and not drawing such that you can jump through most of the gates safely without risking falling down or suicide. If you stay in the middle 50% of the screen you'll have a much easier time catching gates than if you go outside that area, especially when consecutive gates are on opposite sides of the screen.

When you're playing for score or for the massive jump, it's more important to get your multiplier up than it is to do a few mediocre jumps. As such, you should stay on the screen collecting gates for as long as possible, to get your speed and multiplier as high as you can without losing control. As you'll see in my screenshot below, it takes a really high speed and multiplier to get the 1 million point jump, so it's extremely relevant to build up your speed and multiplier before taking off. And don't worry if you miss a gate; odds are you'll get it back in literally a matter of seconds. If you get to a point where you know you won't be able to get the next gate and you don't want to lose your multiplier, launch yourself in the air and play catch; you'll keep gaining speed as you pass gates, and as long as you hit the first gate you see when you land you'll keep your speed and combo going. The risk to this is that if you come down in the middle of a jump, or you start drawing your snow too far forward, you're liable to kill yourself.

Each red or green gate you jump over when you're off the screen increases you score for the jump. As well, the longer you go without drawing snow, the higher your jump score will be. Jumping tunnels does not affect your jump score any more than jumping a series of jumps does; no green or red gates means no score boost. Jumping at about a 45 degree angle works best, and it will take practice to get the timing right.

In order to get the 1 million point jump, you need to jump over about 10-12 gates without drawing snow, with an enormous multiplier. You also have to land the jump, or it won't count. I've made three 1 million point jumps, my highest being 1.3m, and I got a screenshot of my stats almost immediately after landing the first one. That screenshot is below. My speed and multiplier were both well over 100, though the multiplier is more important. The 488,278 label there is from the gate I buzzed after landing, and you'll notice another 428,315 from a non-perfect tunnel right before my jump; large multipliers are very good.

A note on being airborne: refraining from drawing snow does not affect your score when your Solipskier is in the visible part of the play area, but it does prolong your multiplier when you're going for a while without a gate to go through. There is no bonus for doing tricks where you can see them, and the number of points you get for buzzing a tower is unaffected by whether you're drawing snow. However, letting go of that mouse button is a surefire way to make sure your Solipskier is airborne. As such, once you're in the air there's no reason not to draw snow, provided you can see your Solipskier and you have gates visible in front of you. Also note that your snow will appear behind your mouse cursor, not under it. How far behind it varies with your speed. Keep this in mind when planning a landing from a jump

Unfairnesses:
About 10-15% of the time, a red gate that kills you will show up immediately after a tunnel, and if you're going too fast you won't have time to react. When this happens, it doesn't matter how well you're doing in the tunnel, you are almost always forced to either bail early into a jump or die. The positioning of the red gate should be taken into account here, though, as there's no need to jump a gate that you're going to miss anyway. About 3-5% of the time, a red gate will appear with significantly less warning than you're meant to have. Be on the lookout, and if you don't see anything indicated by the 2/3 point of the tunnel, be extremely wary and ready to jump.

For some reason, passing a red gate without dying doesn't do anything to prolong your multiplier. That means if you hit a tunnel at low speed immediately followed by a red gate, and you don't jump off the screen, you're going to lose your multiplier.

The jumps and gates are generated randomly, which means sometimes you'll get something that just can't be done at your current speed without a lot of practice. I've seen 12 red gates in a row at heights with enough variability that all I could do was hang out at the top of the screen and wait for them to pass, I've seen red gate and jump combinations that are impossible at low speed, and I've seen huge air jumps that go completely over two tunnels in a row. When you're facing a series of red gates and jumps, try to keep jumping off-screen. Passing the red gates off-screen will keep your multiplier and speed going, and keep you from having to restart at 1.

Sometimes your multiplier will vanish on you for no apparent reason while you're doing a huge air jump over jumps and tunnels. Again, there's nothing you can do about this.

In my ideal world, red gates would extend your multiplier and there would be a limit to how many times you can see them in a row. Unfortunately, it's not my game, so I don't get to make that call.

Number Observations:
70kph seems enough to skim past a jump

multipler and speed = perfect tunnel score (numbers are approximate):
15 and 50 = 170k
42 and 78 = 1.6m
57 and 91 = 4m
63 and 98 = 5m
72 and 106 = 7m
90 and 120 = 12.6m
95 and 126 = 15.7m
100 and 132 = 16.5m
120 and 150 = 24.5m
137 and 168 = 38m
165 and 190 = 67m
173 and 203 = 73m
180 and 210 = 82m
190 and 220 = 97m

Summary:
Basically, this is a game that just requires patience. You can get the 1m jump score by waiting until you have a high enough multiplier and speed, and you can literally get the 50m (100m) medal by just letting your guy chill out for a couple hours while you draw enough snow to keep him from crashing. That's boring and takes forever though, so I don't recommend it.
