About this game

Solsticio is a calm, elegant logic puzzle you can understand in three seconds and
play with one hand. Fill every grid with two symbols — sun ☀ and moon ☾ — using
pure logic. If you follow the rules, you never have to guess.

THREE SIMPLE RULES
• No three in a row: never three suns or three moons in a line, across or down.
• Balance: every row and column holds the same number of suns and moons.
• Connectors (= and ×): later levels add clues between cells — same or different.

Every puzzle has exactly one solution, verified by the game. No luck, no dead ends —
just satisfying deduction.

A NEW PUZZLE EVERY DAY
Play the Daily Puzzle — the same board for everyone, everywhere — build a streak,
and fill your monthly calendar. Perfect for the commute, the queue, or the sofa.

RELAX, DON'T RUSH
No lives. No energy. No timers breathing down your neck. Solsticio never makes you
feel rushed or stuck: hints teach you the next step instead of solving it for you,
and a gentle nudge appears if a level gives you trouble.
