About the game

The field is six columns wide and twelve rows tall, and it is filled with three kinds of block: circles, triangles and squares. You always hold a pair of them, one on top of the other. Move the pointer over a column and a ghost of the pair appears on top of its stack; tap there to drop it in. Tapping anywhere else swaps the order of the two blocks in your hand.

Line up three or more blocks of the same shape, across or up and down, and they light up. That is only the start of the move. After a moment the lit blocks change into other shapes, and if the new shapes happen to line up with their neighbours, the chain goes on, with a multiplier that grows with every link. In the end everything that was lit disappears, the columns above it fall, and the score appears for a moment on the left as the number of blocks times the multiplier. A short chain pays little. A long one pays a lot.

You are not alone in filling the field. Under the stack there is a purple meter, and while it fills it shows the next row of blocks that will be pushed in from below. When it is full the row comes in and everything goes up one step. You can tap the strip yourself to bring the row in early, which feeds you more blocks to build with at the cost of space. The game is over when no column has room left for your pair. is one of the one-button mini-games that Kenta Cho, who works as ABA Games, makes with his crisp-game-lib library. There are no image or sound files: the graphics are drawn by the code, and the sound effects and music are generated while you play.

A few things worth knowing

Plan the chain, not the line. Because lit blocks change shape before they vanish, it pays to leave places where the changed shapes will meet their neighbours.

Space is the real timer. Bringing the next row in early is risky, but a short field with nothing to match is no better.

Look at the ghost. Only columns with room are offered, and the pair shown is the one that will land.
