How to play

Goal. Fill every square with a seed or a sprout so each row and column is balanced, with no three alike in a line and no two lines the same.

Planting

Each row and each column holds the same number of seeds and sprouts: three of each on 6 × 6, four on 8 × 8, five on 10 × 10.
Three seeds or three sprouts never sit next to each other in a row or column.
No two rows match exactly, and no two columns do. Plants that break a rule are marked.
Tap a square to cycle seed, sprout and empty. On a keyboard, 1 plants a seed and 2 a sprout.

Pairs and gaps. Two seeds side by side need sprouts at both ends, and a gap between two sprouts must hold a seed. The ringed squares follow from those two rules.
