Soluna

Fill the grid with suns and moons: equal numbers in every row and column, never three in a row, and follow the = / × clues. One unique solution every day, solvable with pure logic — no guessing, no language, no account.

A new puzzle arrives at midnight every day. Difficulty ramps from easy Monday to hard Sunday (8×8).

☀️と🌙を並べる日替わり論理パズル。各行・各列は同数、3連続禁止、「=」は同じ・「×」は違うマーク。答えは毎日1通り、当て推量なしの論理だけで解けます。月曜=易しい→日曜=難しい(8×8)。
