Daily Number
Reach the target by combining number cards. Practice opens directly into the six-number game; specialist review stays below the board when you want it.

Six numbers. One target. Start when ready.
The board stays hidden until you start. Tap a number, an operator, then another number. Every generated round has a verified exact solution.

Know whether the route is still exact — then learn why
Target 6 now verifies the current state after every merge instead of only proving the starting puzzle. Study minimum remaining merges, route family, fixed repeatability, adaptive weaknesses and completed routes. Evidence stays local and task-specific.
Start a Target 6 round
After every merge the local solver checks whether the target is still reachable, how many merges remain at minimum, and the current route family.
No completed Target 6 review yet.
Finish a Target 6 round to keep the result, par and route family here.
Local evidence, not a standardized score
Exact rate, timing, moves over par and hint use describe only your local play on this page. They are not IQ, ability or population comparisons.
Five reproducible streams
Clean-5 requires one uninterrupted, hint-free A, B, C, D and E. Repeating a memorized stream does not qualify.
Start Fixed Target 10, Adaptive Route Drill or Custom Target Drill.
Control large numbers, target range and run length
Every generated drill is solver-verified before play. Custom and adaptive runs never enter Clean-5.
