KTO
A crisp little number puzzle - fold four cards into exactly 24. Tap a number, tap an operator (+ - x /), then tap a second number to combine them into a new card. Keep going until one card is left. Make it 24 and the level is yours. Ten levels that grow from tidy whole-number sums to puzzles that only crack open with division and fractions.
ALWAYS SOLVABLE, ALWAYS FAIR
Every deal is generated by seed and pre-checked by a real solver before you ever see it - so a way to make exactly 24 always exists and the same level is the same for everyone.
STARS, COINS AND A SHOP
Reach 24 under the par time with no misplays for up to three stars, and earn coins. Spend them in the shop and claim a small free gift. Everything is earned in-game - no pay-to-win.
MADE TO THINK
Clean violet colors, soft number cards, undo and reset always at hand - a few satisfying minutes of mental math whenever you have them.
