The icefall
Camp is pitched at the foot of an icefall, and the glacier is restless. Blocks of ice are tumbling down the chute, one after another, in seven shapes.
Turn them and fit them together. Fill a row from wall to wall and it calves away down the glacier. Clear four rows with one block and that’s a Calving, the biggest score there is.
Every ten rows the ice comes down faster. Let the pile reach the top and the icefall buries the camp.
The next three blocks are always on the board. Put one aside with Hold when it doesn’t fit, and swap it back in later.
On a phone, drag left or right to move the ice, tap to turn it, drag down to hurry it and flick down to drop it. Flick up to hold.
Keep the camp clear.
