Mega-Gorok has locked the Grid: every square holds a number prisoner. Raxo needs the child's help to set them free, one right answer at a time. For ages 9 to 10, with no ads and no account to create.
Three modes
Creative Mode
Step-by-step help: a hint after the first mistake, the next step after the second, the answer after the third.
Beat the Big Boss
No help, to defeat Mega-Gorok. Missed squares come back later for a second chance.
Dictation Mode
Falko reads the sums out loud; the child writes the answer.
Thirteen languages
French, English, German, Spanish, Italian, Portuguese, Russian, Japanese, Korean, Chinese, Arabic, Hindi and Indonesian, each with its own calculation tricks.
Everything stays on the device. No personal data collected, no connection needed.
