Finding the current UTC challenge…
A daily challenge you can come back to.
A date always points to the same 10×10 puzzle. Midnight UTC starts a new day, but never interrupts your current grid. Your progress is saved separately from free play.
A daily solve completed on its own UTC date counts toward your streak, with or without hints. Catch-up solves are recorded but do not repair a streak. Reveals do not count as solves. Timing uses your device clock.
