Balance Ember and Frost on a 6×6 grid. Equal counts in every row and column, no three-in-a-row, and honor = / ≠ neighbor clues.
📖How to Play
Duo Puzzle is a two-symbol logic grid. Fill every cell with Ember (●) or Frost (▲).
Each row and each column must contain the same number of each symbol. You may never place three identical symbols in a straight line horizontally or vertically. Some neighboring cells show = (must match) or ≠ (must differ). Some cells start filled as givens.
Tap empty cells to cycle empty → Ember → Frost → empty.
🎮Gameplay Mechanics
1. Equal Counts
- On a 6×6 board, every row and column needs exactly three Ember and three Frost.
2. No Triples
- Never allow ●●● or ▲▲▲ in a line — horizontally or vertically.
3. Relationship Clues
- = between neighbors means both cells share the same symbol.
- ≠ means the two cells must be different symbols.
4. Givens
- Pre-filled cells are locked and cannot be changed.
- Use them with the edge clues to deduce the rest.
5. Win Condition
- The board is full, balanced, free of triples, and every = / ≠ clue is satisfied.
💡Tips for Success
1. Finish Near-Full Rows
- A row with five filled cells often forces the last symbol by balance.
2. Block Triple Threats
- If two matching symbols already sit together, the cells on both sides cannot match them.
3. Read the Edges
- A = clue next to a given immediately fills (or constrains) its neighbor.
4. Use Check
- Highlight conflicts anytime a placement feels risky.
