Avalanche watch
The storm has loaded the high slopes with more snow than the mountain can hold. Somewhere above the valley, the first crack has already run.
Below you, six huts are full of climbers waiting out the weather. Between them and the mountain stand three snow cannons, and you.
Boulders and snowballs are sliding down toward the huts. Tap the sky ahead of them, and the nearest cannon fires a charge there. Its blast breaks up anything that slides into it, and each boulder that breaks bursts in turn. Line them up for a chain.
The centre cannon fires fastest. Each cannon has ten charges a wave, so don’t waste them. Big boulders are worth double, and some boulders split in two on the way down.
Every wave comes faster than the last, and is worth more. Huts and charges left at the end of a wave earn bonus points, and every 10,000 points rebuilds a hut.
When the last hut is buried, the game is over.
Tap the sky. Save the huts.
