Beginner strategies for the Green Dot board
Three foundational moves that turn a twenty-five-minute solve into a ten-minute one. Sign in to your Green Dot account, open today's board, try them.
1. The two-yellows deduction
Every row and every column contains exactly one yellow dot. If you see two yellow dots in the same row or column, one of them must be wrong. When you spot a row that already contains one yellow, every cell in that row is disqualified from also being yellow — mark them mentally as "green-or-empty". Doing this on every row and column takes ninety seconds and cuts the search space in half.
2. The corner rule
Corners are constrained by two rows-columns at once. If both the top row and the leftmost column already have their yellow dot, the top-left corner is definitely not yellow. If in addition the top row already has both greens, the corner is definitely empty. Corners resolve first on almost every medium-difficulty board.
3. The parity trick
Each row has two green dots. Count filled cells across a row; if it is already two, mark the remaining three cells as empty-or-yellow (one of them is the row's yellow). If it is zero, both greens are still to place — but only in the three cells not yet marked. Applying parity everywhere shortens the deduction chain typically by three or four steps on medium boards.
