How today’s board is solved
Step by step, with no guessing. Every move below follows from the ones above it.
This board needs 28 deduced moves: 12 × no-three-in-a-row, 10 × line balance and 6 × contradiction.
Careful: this is the full reasoning. Play first if you would rather work it out yourself.
- E1 — the two cells before it are suns, and three in a row is not allowed, so it has to be a moon
- E2 — the two cells before it are moons, and three in a row is not allowed, so it has to be a sun
- C5 — the two cells before it are suns, and three in a row is not allowed, so it has to be a moon
- E5 — the two cells before it are moons, and three in a row is not allowed, so it has to be a sun
- F5 — the two cells before it are suns, and three in a row is not allowed, so it has to be a moon
- A5 — that line already holds all the suns it can take, so the rest are moons
- E6 — that line already holds all the moons it can take, so the rest are suns
- D6 — the two cells before it are suns, and three in a row is not allowed, so it has to be a moon
- B1 — putting a sun there breaks the board a few moves later, so it is a moon
- B2 — putting a moon there breaks the board a few moves later, so it is a sun
- D2 — putting a sun there breaks the board a few moves later, so it is a moon
- A2 — putting a moon there breaks the board a few moves later, so it is a sun
The remaining 16 moves follow the same way.
Three simple rules
- No three in a rowNever three suns or three moons in a line, across or down.
- BalanceEvery row and column holds the same number of suns and moons.
- Connectors (= and ×)Later puzzles add clues between cells — same or different.
