Min moves = the true fewest taps possible for today's grid, not a guess.
That's today's grid done — see the countdown to tomorrow's up top.
How to play
The whole grid is visible from the start — nothing's hidden. Some cells are already lit (dark), some aren't.
Watch the dots beside each row and below each column. A dot is amber if that row or column currently has an odd number of lit cells, and green if it's even.
Tap any cell to toggle it on or off. This instantly flips both its row's dot and its column's dot.
You have a limited move budget per attempt — a little more than the true minimum for today's grid. Watch "moves left" count down.
Get every dot green before you run out of moves. If you don't, that attempt ends and the board resets fresh — you get up to 6 attempts a day.
Made an early mistake? "Give up attempt" ends the current one immediately rather than making you burn through every remaining move — but it does count as one of your 6.
Solve it (or use all 6 attempts), then share your result — a row of colored squares for every attempt, copied straight to your clipboard.
Every toggle flips exactly one row-dot and one column-dot together — so pairing up two amber dots (one row, one column) with a single tap is usually your most efficient move.
