A problem appears above the board and four numbers scatter across the grid.
Steer the snake onto the correct answer.
A correct answer grows the snake three segments. A wrong one shrinks it two, so a mistake costs length, not the run.
Five correct answers raise the level, and the snake speeds up.
How do I steer?
Use the D-pad below the board.
Or tap anywhere on the board to turn the snake toward that spot.
The two modes
Normal — addition and subtraction from the first level, with multiplication unlocking at level seven. Numbers start as single digits and grow to fifteen as you climb. Three lives per run.
Starter — count 1, 2, 3 in order. No lives are lost. Built for children who are still learning their numbers.
Sound
Tap the speaker button at the top of the game screen to mute or unmute.
The setting is remembered the next time the app opens.
Nickname and the leaderboard
The nickname on the home screen is optional and only labels entries on the
leaderboard on that device. There is no online leaderboard, no account, and
nothing is sent anywhere.
My scores disappeared
Scores, the nickname and the sound setting are stored on the device only,
with no account and no backup to us. Deleting the app removes them, and they
do not transfer to a new device.
For parents
No ads, no in-app purchases, no subscriptions, and no sign-up.
The app makes no network requests. It works entirely offline.
The About screen sits behind a multiplication problem, so app information stays reachable by grown-ups only.
After every run, an accuracy breakdown shows how each operation went, so you can see whether it is subtraction or multiplication that needs work.
