Classical Game 24 is the beloved "24 points" math card game, faithfully rebuilt for iOS by Honest Games. THE GOAL You're dealt 4 cards (1–13). Use ALL four cards exactly once with +, −, ×, ÷ and parentheses to make exactly 24. Simple to learn, endlessly deep to master. TWO WAYS TO PLAY • Expression — tap cards and operators to build a full equation, then submit it. Supports implicit multiplication and an Undo button. • Merge Cards — tap a card, an operation, then a second card: the two fuse into a new card showing the result (exact fractions, never ugly decimals!). Keep merging until one card reads 24. Switch styles anytime — even mid-game — from Settings, right on the game screen. THREE MODES • Time Attack — choose your own total time (1–5 minutes) and solve as many hands as you can. • Speed Run — choose 15–60 seconds per hand. Every solve deals a new hand and resets your clock. One slip and it's over. • Practice — no timer, no pressure. Take all the time you need and swap cards whenever you like. FEATURES • Every hand is guaranteed solvable • Exact fraction arithmetic — 28÷11 shows as 28/11, with zero floating-point errors • Undo works in both play styles (even splitting cards back apart after a merge) • In-game settings that never pause the clock in timed modes • Quit anytime with a clear warning that your run won't be saved • Private records page with your history, and safe multi-select deletion with confirmation • Four languages: English, 中文, Español, Français • No ads. No accounts. No tracking. Train your mental math, sharpen your speed, and see how many points you can rack up. Download Classical Game 24 and make 24!
