Read the current, plan each release, and bring every basin to its goal in a collection of 60 compact logic puzzles.
Each move sends one drop into the adjacent basin. The tide reverses after every valid move, so the order of your choices matters. Watch the current and goal counts together, then decide which basin to tap before the step limit runs out.
The level book introduces four-basin puzzles first, then adds larger layouts and a clockwise-only release rule. Later studies invite you to improve your step count. Replay completed levels whenever you want to test a different sequence.
Your unlocked levels, best step counts, and an unfinished board are saved on your device. Pause at any time and return to the same puzzle when it suits you. The game can be played offline.
Plan each drop through 60 tide-shifting basin puzzles.
