How to Play Countdown Numbers
- Read the target number: Each round gives you one target number and six number tiles. Your goal is to build an arithmetic expression that equals the target.
- Combine the number tiles: Use +, -, ×, ÷ and parentheses to combine the numbers. Try to create useful intermediate values before writing the final expression.
- Follow the number-use rule: In this version, all six number tiles must be used exactly once. A correct value is not enough unless the expression also follows this rule.
- Submit the final expression: When your expression equals the target number, submit it to complete the puzzle. If you get stuck, use the scratchpad to test smaller calculation paths.
Online Countdown Numbers: Target Number and Arithmetic Practice
Countdown Numbers is a target number puzzle. Each round gives you several number tiles and one target, and your task is to combine the tiles with arithmetic operations to make an exact expression.
This online version is designed for short practice sessions. You can train mental arithmetic, number sense, and expression-building strategy before trying the Countdown Numbers Daily Challenge.
Countdown Numbers Calculation Tips
Good Countdown Numbers strategy is not just about trying random operations. Start by looking for useful intermediate numbers, then use large tiles for scale and small tiles for final adjustment.
Build an intermediate target first
Do not chase the full expression immediately. Try making a nearby intermediate result with two or three numbers.
Use large numbers for scale
Large numbers often move you close to the target, while small numbers are useful for final adjustment.
Watch multiplication and division jumps
Multiplication can quickly grow a value, and division can bring an oversized value back into range.
Use each number exactly once
A correct value is not enough. The final expression must use every given number exactly once.
