N1 Bet

N1 Bet
N1 Bet is a quiet logic puzzle about balance. Every level is a grid where some cells already carry a fixed clue - black or white - and the rest are yours to fill in. Tap an empty cell to cycle it through black, white, and back to empty.

Two rules govern every grid, and they never change: all the black cells must join into a single connected shape, and all the white cells must too - no color may split into a second island. And no square block of four neighboring cells may ever turn a single solid color. Satisfy both rules across the whole board and the level is solved.

Every one of the twenty grids is generated to have exactly one correct answer, verified by a solver before it ever ships, so there is always a real, findable solution - never a guess. The grid grows from a small five-by-five opening puzzle up to a demanding nine-by-nine board by the end, asking for sharper reading of the same two simple rules rather than new ones. Undo and Reset are always free, and a Check pass will point out a broken block or a stray island without giving the answer away.

There is no clock pressure and no way to lose outright - only a board waiting to be balanced. Coins are earned by solving cleanly and quickly, and nothing here is ever sold. Just black, white, and the space between them.
