DONE FOR TODAY
LAST 14 DAILY SCORES
ONE SEED, ONE WORLD
The UTC date generates the challenge. Nobody gets an easier Tuesday, and the same date always regenerates the same run.
ONE RECORDED ATTEMPT
Only the first completed run of the day is recorded in this browser. Grinding until perfect would make the number meaningless.
A DIFFERENT KIND EVERY DAY
The five-game rotation covers estimation, geometry, timing, memory and perception. Continue with any of the 96 practice challenge levels after your Daily run.
NOTHING TO SIGN UP FOR
The streak lives in one browser key. Clear your storage and it goes; export it first if you care about it.
