Four24: Make 24 Card Game

Four24 is the classic make-24 card game, rebuilt for one thumb and zero noise. Every round deals four number cards (1 to 13). Use + - x / and parentheses to make 24 - and you must use all four cards. Fractions are exact, so clever lines like 8 / (3 - 8 / 3) = 24 work the way they should. STAGE MODE 300 handcrafted levels across 15 stages, from gentle warm-ups to proper brain-teasers. Medals for your best runs, levels unlock as you clear them. SPEED MODE Ten fresh puzzles, three minutes. How many can you solve? BUILT FOR REAL LIFE - One-hand mode: cards, expression and controls all drop into thumb reach. - Flexible input: brackets gray out when they can't help, tap ) to close one group at a time, and unfinished brackets are auto-closed when you solve. Tap a used card to pull it back out. - Live evaluation: the strip shows the running value of your expression as you build it. - Stuck? The hint button shows one valid solution.
