Tidecaller

Tidecaller replaces the match-three reflex with a planning problem. Each board is a drowned island where you open and close channels to move water where it is needed. Water obeys the same three rules on every board, and the difficulty comes from the shape of the island rather than from hidden mechanics.

There is no move limit and no timer. A board is either solved or not, and every board has at least one solution that uses fewer channels than the one most players find first — the game records both.

Seasonal chapters add new terrain behaviours rather than new currencies. Salt marsh absorbs, basalt reflects, and ice changes state across turns.
