Arithmetic meets card sorting
Solve addition, subtraction, multiplication and division, then group cards by answer. Tap or drag to move each card.
Try a different move
The move target determines your stars. Free unlimited undo lets you try a different sequence and aim for fewer moves.
A daily arithmetic routine

Questions, answered
Do I fail if I exceed the move target?
No. The move target determines your stars, and you can keep playing until you finish the remaining cards.
Do I need to watch an ad or pay to undo?
Undo is free and unlimited. You do not need to refill it through ads or purchases.
Can I play without an internet connection?
Levels, daily training and progress work offline. Ads and purchases require an internet connection.
When do ads appear?
Interstitials do not interrupt a board. They may appear between boards, and a banner may appear below the game. The ad-removal purchase removes banners and interstitials; optional rewarded ads remain available.
