About the game
Wipe the whole board. That's the job. Two numbers go away when they're twins or when they add up to 10, and a row you empty completely disappears with them.
Matching groups share one color, so you can scan for pairs without doing math in your head the whole time. Run dry? ADD drops a fresh wave of numbers onto the board, and HINT points out a pair you walked right past. Four difficulty modes are there if you want it harder, and the Daily Challenge hands out monthly trophies. Playing also levels up Calculation, Observation and Focus.
How to play
- Press on one number, then another, with a mouse or your finger. They link if they're equal or add up to 10.
- Nothing can sit between them. The line can go sideways, up or down, diagonally, or jump off the end of a row and pick up at the start of the next.
- Out of moves? Hit ADD to bring in new numbers, or HINT to see a valid pair.
- Every number gone means the stage is won. No keyboard needed.
