Two Tone
Fill every square with a sun or a moon. Never three alike in a line, each row and column half and half, and = or × between two squares means same or different.
About Two Tone— the rules, and the twist
Fill every square with a sun or a moon. Never three alike in a line, each row and column half and half, and = or × between two squares means same or different.
Every square takes a sun or a moon. No three alike may sit in a line, every row and column ends up half and half, and the = and × signs between squares say whether two neighbours match. Every board has exactly one answer, and deduction alone reaches it.
The twist: Two symbols sounds like a coin toss, but "never three in a row" turns every pair you place into a chain of forced squares.

Two Tone in short
Every square takes a sun or a moon. No three alike may sit in a line, every row and column ends up half and half, and the = and × signs between squares say whether two neighbours match. Every board has exactly one answer, and deduction alone reaches it.
- 1.Suns and moons. Tap an empty square to place a sun, again for a moon, a third time to clear it. The shaded squares are given and cannot change.
- 2.Never three in a row. No three suns, and no three moons, may sit side by side — across or down.
- 3.Half and half. Every row and every column ends up with as many suns as moons.
