The 24 Game is a classic mathematical puzzle: given four numbers, use addition, subtraction, multiplication, and division — each number exactly once — to make the result equal exactly 24. It sounds simple. Cards like 1-2-3-4 or 2-3-4-6 have obvious solutions. But many four-number combinations require creative use of operations, unexpected orderings, and sometimes fractions as intermediate values — and some combinations have solutions that take even experienced players several minutes to find.
Cliko Games offers seven difficulty levels from Beginner through Cyborg. Lower difficulties use smaller numbers with many valid solutions; higher difficulties use larger numbers and combinations that have only one or two solutions, demanding creative use of division chains and parentheses. Each session consists of five rounds — solve as many as you can before the timer runs out.
Tap a number card to add it to your expression, then tap an operator (+, −, ×, ÷) and another number. Use parentheses to control the order of operations. When your expression uses all four numbers, tap the "= 24 ?" button to check. If you get stuck, use a Hint (3 per session) or Skip the puzzle with no penalty. The Daily Challenge gives every player worldwide the same puzzle — solve it to build your streak!
The 24 Game has been a classroom staple and competitive math sport since its invention by Robert Sun in 1988. The premise is elegant: four numbers, four operations, one target. It trains mental arithmetic, algebraic thinking, and creative problem-solving in a format that works for ages 8 to 80. Competitive 24 tournaments are held worldwide, with students racing to slam the card first.
This free online version on Cliko Games brings the full experience to your browser — no download, no login, no app required. Play on your phone, tablet, or desktop. Challenge friends with a shareable link, compete on the daily leaderboard, and push your skills from Beginner all the way to Cyborg difficulty. Whether you are warming up for a math competition or just killing five minutes, The 24 Game delivers a satisfying mental workout every time.
The 24 Game is the purest arithmetic sprint I know: four numbers, four operators, one target. Make 24. It's the kind of mental math I grew up on — the South Indian classroom fed us number puzzles like this as a matter of course, and I loved them then the way I love them now — and building it for the browser surfaced a problem I genuinely didn't expect: the hard part wasn't the puzzle. It was the typing.
Think about what the game asks of you. On a four-number puzzle you compose an expression fast — numbers, operators, maybe a bracket's worth of intermediate thinking — and you do it in seconds, often on a phone, often mid-streak with the clock breathing on you. Every online math game I studied handled this with a wall of tiny buttons, and every wall of tiny buttons turns a thinking game into a fat-finger game. So the input became this build's real project: a digit-buffer entry that lets you tap numbers and operators in sequence, exactly as you think them, and edit cleanly when a thumb slips. Quick and forgiving, instead of cramped and punishing. Of everything on this page, that entry system is the call I'm proudest of — because the game should test your arithmetic, never your dexterity.
Now the arithmetic itself, and the mistake nearly everyone makes: reaching for multiplication first. It's pure instinct — 24 is a big number, multiplication makes big numbers, so players hunt for the big product straight away. Six times four, eight times three, done whenever it works. But many hands don't contain a clean product, and those are exactly the hands that stall people for a full minute — because the solution runs through division or subtraction to manufacture an intermediate value first. The classic patterns: make a 1 (say, from two equal numbers divided) so you can multiply something by it harmlessly at the end; or build an 8 from awkward parts so a waiting 3 can finish the job. The pros don't ask "what multiplies to 24?" They ask "what small, useful integers can these pairs produce?" — a 1, a 2, a 3, an 8 — and assemble the answer from there.
So train the reversed habit: before hunting products, scan the pairs for small-integer potential. Two numbers close together suggest subtraction; a divisible pair suggests a clean quotient. The hands that look impossible almost always hinge on one unglamorous intermediate step that multiplication-first thinking walks straight past.
The daily hand lands at midnight, the same four numbers for everyone. Fast entry, small integers first, and 24 stops being a wall and becomes a rhythm.
One extra drill that pays off fast: when a hand solves easily, solve it a second way before moving on. Most hands hide two or three distinct routes to 24, and hunting the alternates is what builds the pattern library that makes the hard hands fall.
