How to play

Pick a column to drop the next number. It lands on top of the stack. Every touching block with the same number, up, down, left or right, is pulled in and the number doubles.

If the new number matches another neighbour, it merges again. After that, blocks fall and any new matching pairs merge too, so one drop can set off a long chain.

New blocks are 2, 4 or 8. You always see the next one. Your score is the total of every number you create. The game ends when every column is full.

Tips & strategy

Always check the next block before you drop. Pick the column where the current block merges and leaves a good spot for the next one.
Stack from the bottom up as 32, 16, 8. Dropping an 8 on top then doubles its way down the whole column.
A block merges with everything equal around it at once, but only doubles once. Merging three 8s gives a 16, not 32.
Keep at least one column low. When the board fills up, that column is where you rescue awkward numbers.
