Salmon Leap

Swim a salmon home. Start at the estuary and head upriver through five stretches of water to the spawning ground, before the clock runs out. On the way are four waterfalls, floating logs, boulders and one hungry bear.

One button

• Hold it to dive. Let go to rise. The deeper you dive, the higher you leap.
• In the air, hold to flip, and let go before you land, nose first. A clean entry scores the trick and gives a burst of speed; a belly flop resets your multiplier.
• Before each waterfall, dive to the bottom of the pool and let go when the dotted arc clears the lip.

Rings add points and a little time, and every ring or clean flip fills the multiplier, up to ×5. A run takes about ninety seconds. Time left at the end becomes points, and every finish is graded S, A, B or C. The result screen draws a picture of your run to save or share.

Controls: Space, an arrow key, the mouse button or a finger on the screen. P pauses, M mutes.
