Domino Grid gives the entire forum the same compact deduction puzzle each day. Players fit ten dominoes across a four-by-six board with its four corners removed, filling all twenty active cells while satisfying every colored region and fixed pip clue.
Each region carries one exact rule. Its cells may need to add to a displayed total, contain all equal values, contain all different values, or keep every pip above or below a target. Small numbered markers lock individual cells to fixed values. A domino can fit physically and still break several overlapping deductions, so solving the board requires more than matching pieces to spaces.
The addon runs the entire game automatically. Its local generator builds a randomized perfect tiling, selects ten unique pieces from the double-six set, includes every pip value from zero through six, and mixes doubles with ordinary dominoes. Before publication, the built-in solver verifies every region, every fixed clue, the stored answer, and exactly one complete solution. Previously published puzzle keys are rejected.
Daily standings rank no-hint solves first, followed by elapsed time, move count, and completion order. All-time standings collect the strongest completed results across every published puzzle. Personal records track games played, completions, perfect no-hint solves, average and best time, current streak, and best streak. Community totals show starts, completions, and average solving time.
