Topple It!

Every level asks one question: which block, and which way?

Tap a block and it falls the way you aim it, flattening the tiles in front of it. Whatever it lands on goes down too, in the same direction, however far the chain runs. One good tap brings down half the board. One careless tap clears three tiles and strands the rest.

If you ever set up a line of dominoes just to knock it over, this is that — except you only get so many pushes.

■ HEIGHT IS NOT DECORATION
Blocks come in different lengths, and length decides what a block can reach. A tall one falls across several tiles, so it can knock over something with a gap in between. A short one never reaches past its neighbour. Working out which block bridges which gap is most of the game.

■ ORDER IS EVERYTHING
Where a row and a column cross, they share a block, and only one of them can have it. Take the wrong line first and the other falls apart in your hands. There is usually one order that works and a dozen that cost you a tap.

■ THE BOARD REFILLS
New blocks arrive as you clear, several at a time, in groups lined up so one well-aimed tap takes all of them together. The later boards keep opening up almost faster than you can empty them.

■ NO PHYSICS, NO DICE
The same tap always does exactly the same thing. Nothing wobbles, nothing bounces, nothing is decided by a random roll. When a level beats you, the answer was on the screen the whole time.

■ WHAT YOU GET
• Posts that stop a chain dead, pits that swallow it, arrows that turn it a corner
• A tap budget on every level — spend badly and the run is over
• Coins to spend on extra taps when you come up short
• Every level run through a solver before it shipped, so none of them are impossible

Built for portrait, one hand, one level at a time.

Topple It! is a puzzle game about consequences. Nothing is hidden and nothing is random. The only thing between you and a clean board is whether you looked before you tapped.
