Tide Tiles
Tide Tiles is a binary logic puzzle that plays in the browser on phones, tablets and computers, for one player. It has a daily challenge, the same for everyone that day.
Fill the grid with shells and waves so no three alike sit in a line and every row and column is half and half, with marks showing which neighbours match or differ. Every grid has exactly one answer; the first twelve are 6×6, then 8×8. The daily storm grid lifts the half-and-half rule from one row and one column.
How to play
- Tap a square: shell, then wave, then empty again
- No three alike in a row or column, and each line is half shells, half waves
- = between squares means the same, × means different. There is one answer
The game shows these steps as you play, the first time.
Controls
- Tap a square to cycle shell, wave, empty
- = means the same, × means different
- ?daily=1 for the storm grid
Tips
- Wrong squares tint at once, whether three in a line, a line past half, or a broken = or × mark, so a tint means undo rather than press on.
- Every grid has exactly one answer, so a square is never a free choice; if both shell and wave seem to fit, something elsewhere on the board decides it.
- Grids 1 to 12 are 6×6 with 3 to 6 marks; from grid 13 the board is 8×8 with 5 to 9 marks and the same rules.
What is the storm grid?
The daily puzzle, the same 6×6 for everyone that day. One row and one column, each marked with a cloud, are let off the half-and-half rule; everything else holds, including no three alike and the = and × marks. It has a single answer and keeps its own streak.
Does progress carry over?
Yes. Grids are numbered, each one solved opens the next, and the number you have reached is kept, so the first twelve 6×6 grids give way to 8×8 grids as you go. The daily storm grid sits apart from the numbered run and does not change your place in it.
