About the game
Six new StoStone puzzles every day. The black cells in a region must connect, a number says how many there are, neighbouring regions may not touch with black cells, and when the stones fall they must cover exactly the lower half of the grid.
Daily StoStone belongs to the Puzzle of the day variant in the Daily challenges world and joined the catalogue on June 29, 2021. The rules, levels and on-screen language are set by the game’s creator, and a short guide appears on its start screen.
How to play
- Read the puzzle rules on the start screen.
- Solve today’s puzzle.
- Come back tomorrow for a new one.
Tips for a better game
- If you do not know the rules, read the in game help first, many of these are lesser known Japanese logic puzzles.
- Start with the easiest size or difficulty and climb as you get used to it.
- In logic grids, enter only what you know for certain, guessing takes its revenge later.
