A calm number-shading puzzle under a drifting aurora of mint, lilac and peach, with huge numerals and almost no frames. Tap a cell to shade it, tap again to mark it as kept, once more to clear it. Here is the whole thing in figures. 5:00 The Sprint clock. Solve as many puzzles as you can before the light fades. Boards grow from 5×5 to 8×8 as you go, the final 30 seconds turn red, and Skip moves past one that stalls you. Your record and bars for recent sprints sit on the Sprint page. 6 sizes Zen has no clock pressure. Pick 5×5 up to 10×10 with a chip, solve, and the next board arrives straight away. Counters track each size. 3 rules No number twice among unshaded cells of a row or column. Shaded cells never touch side by side. Unshaded cells stay in one connected area. Each board has a single answer. 25 entries The Archive lists your last 25 solves with mode, size, time and hints used. 10 of 22 The Quiz asks 10 questions from 22 real facts about the history of logic puzzles: Number Place in 1979, Euler and his 36 officers, the craze for sliding tiles in 1880, the Tower of Hanoi and more, with a note after each answer. 6 badges Stats show puzzles solved, the longest sprint, thinking time and hints, plus Zen bars by size and six badges from Clear sky to Puzzle historian. 1 switch Three soft pools of colour circle and breathe while thin lines drift down behind the pages. The Background animation switch in Settings holds them still; haptics and a progress reset sit beside it. 0 accounts Plays offline, with no sign-in and no ads.
