Kobadoo Arithmetic

Why We Picked Kobadoo Arithmetic

Kobadoo Arithmetic puts the board and the space left on it on one screen and then lets the board do the arguing. A run can end quietly: no explosion, just a shape that no longer has anywhere to go. What makes it work is how little it asks you to hold in your head at once. It has been played 408 times here — modest beside the arcade titles, and about right for a puzzle. The page's own numbers: 130 of 172 on the puzzle shelf, and 5.0 out of 5 from 10 ratings.

How to Play

The page documents very little, so these are the things worth knowing before you spend time on it:

• A game that runs at a fixed size will not fill a large monitor, and that is normal.
• Clear whatever the level asks you to clear, and count the space that the clear gives back.
• Hold the board in your head; writing it down is slower than reading it.

Editor’s Note

Tutorials are rare on this shelf, which is either the point or the problem depending on why you came. These pages keep the game and its text side by side, so a rule that reads obscurely can be checked against the board.
