A make-10 number game styled like an engineer's drafting tool: a dark grid, monospaced digits and a blue selection frame with a live Σ counter. Six powers of 10 cover the whole thing. 10⁰ · The rule Drag a rectangle across the grid. If the digits inside add up to 10, they clear. Empty cells count as zero, and bigger rectangles and fast streaks score more. The frame turns cyan at exactly 10 and red when the total runs over. 10¹ · Zen An 8 by 12 field that refills as soon as cells clear, so a move always exists. There is no clock; end the session whenever you like. Your record and average are kept. 10² · Sprint The same field against 60 seconds, with a time bar that turns red in the final stretch. Record, longest streak and your recent runs are listed. 10³ · The quiz Twenty-four real facts about the number 10, the decimal system and counting: the Roman X, binary 1010, the googol, Liber Abaci from 1202, a perfect score in 1976 gymnastics, the metric system and the decimal point. Rounds of 10 questions, four options each. 10⁴ · Log Six numbered metrics, a line chart of scores and a table of the last 15 sessions with mode, score, tiles and time. 10⁵ · Sys Haptics, a reset with a confirmation card, and the animated drafting grid with a cyan scan line sweeping down, which can be switched off in Settings.
