Rules
Targetsum is the numbers game against the clock. Each draw gives six numbers and a target between 101 and 999. Pick two numbers and an operation: the result replaces both numbers and can be used again. A subtraction stays positive, a division must be exact. Every target can be hit exactly.
- Your score is your total time over the 5 draws, plus 10 s per point away from a target (at most 10 points per draw). On a tie, the smallest total gap wins.
- Stuck? Submit anyway: the number closest to the target counts. The result shows an exact solution for every target you missed.
- Daily challenge: the same draws for everyone, renewed at midnight (Paris time). Only your first run counts for the leaderboard; the next ones are practice.
- Free run: new draws every game, your best run of the day counts.
- With the keyboard: 1 to 6 pick a number, + - * / an operation, Backspace undoes a step, Enter submits the draw.
Targetsum: the rules in brief
Six numbers and a target between 101 and 999: combine two numbers with + − × ÷, the result replaces them, until you hit the target exactly. Five draws against the clock, each point away costs 10 seconds.
Targetsum: how to get better
- Start from the target: look for a nearby multiple of 25, 50, 75 or 100, then fix the gap with the small numbers.
- Stuck? Submit the closest number: 10 seconds per point often beat a minute of searching.
