Countdown Numbers Solver

Enter one target and six number tiles to find exact arithmetic expressions.

Solver tool

Enter puzzle

Use the same format as the Countdown Numbers game: one target, six tiles, and each tile used exactly once.

Target

Enter a target and six numbers, then run the solver.

Check whether a Countdown Numbers puzzle is solvable before spending more time on it.
Compare different arithmetic expressions and learn cleaner calculation paths.
Use it as a practice companion after finishing a daily challenge or a standard game.

Build a nearby intermediate value first, then adjust with the remaining small numbers.
Use large tiles for scale and small tiles for correction.
Try making factors of the target before expanding into long expressions.

Look for target factors such as 3, 4, 5, 6, 8, 10, 25, 50, 75, and 100.
When the target is near a round number, create the round number first and subtract the difference.
Keep expressions readable; a shorter expression is often easier to reproduce in the game.

Does each number have to be used once?

Yes. The solver follows the game rule and searches expressions that use every selected tile exactly once.

Can division create fractions?

Yes. The solver uses exact rational arithmetic internally, so fractional intermediate values are handled safely.

Why are only some solutions shown first?

A puzzle can have many equivalent expressions. The page lists a useful batch first and lets you load more.

Is this the same as the daily game?

The daily game is a timed challenge. This solver is a study tool for checking and learning expressions.
