Make the Target

Use every starting tile exactly once. Combining two numbers creates a new tile. Solve the puzzle by making the final tile equal the target. Tiles with the same number still count as separate tiles.

Add & Subtract uses ＋ and −. Multiply Too adds × and requires multiplication. All Four adds ÷ and requires division. Every intermediate result must be a positive whole number. Zero, negative numbers and fractions are not allowed, so division must be exact.

Yes. Any solution counts if it uses every tile once and reaches the target with the allowed operations. Your result and shared image show the calculations you actually made, in order.

No. If the final number misses the target or you get stuck, undo a calculation and try another path. Undo has no extra penalty, and your solve time keeps running.

Restart this round replaces only the current puzzle with another at the same difficulty, resetting its time, calculations and hint. Completed rounds and later puzzles stay unchanged. Time spent on the replaced attempt does not count toward your final result.

Once per round, a hint suggests one calculation that leads to a solution. If the current combination cannot be solved, it tells you how far to undo first. Each round with a hint adds 20 seconds to your adjusted time.

Each mode has a separate puzzle bank for rounds 1–6. The rounds use 3, 3, 4, 4, 5 and 5 starting tiles. New games avoid recently played puzzles, so you can play fresh puzzles anytime without a daily limit. Replaying the same six puzzles restores the exact set, including any replaced rounds.

Choose a mode on the result screen and select Play again for new puzzles in that mode. Replay the same six puzzles keeps the completed game’s original mode, so a puzzle that needs division is never opened in a mode that cannot solve it.

The timer runs from the moment a puzzle appears until you solve it. It keeps running if you leave the page during a round. Waiting between rounds does not count. All three modes have no time limit.

Progress and records are saved only in this browser and do not sync between devices. Clearing browser data may remove them. If browser storage is unavailable, you can still keep playing on the current page.

Each mode has four titles based on adjusted time. The highest title also requires completing all six rounds without a hint.

Finishing within the top time with a hint earns Skilled Combiner. Your first completion is celebrated separately from a personal best improved by at least 0.1 seconds. A tie does not count as a new best.
