Touhou Star Puzzle: Logic Game
A logic puzzle with Touhou
Free · Designed for iPad. Not verified for macOS.
A new Daily Puzzle: one board a day, the same for every player in the world. Build your streak and beat your best time.
Star Battle, the classic pencil puzzle, played with the characters of Touhou Project.
No pen, no paper. Just one finger and a quiet moment to think.
■ Only three rules
- One character in every row and every column
- One character in every colored region
- No two characters may touch, not even diagonally
Mark the cells you have ruled out with an X and narrow it down step by step.
There is no luck involved. Think it through and exactly one answer is waiting.
■ From 5x5 to 9x9
Start with a gentle 5x5 board. The grid grows as you go, up to a demanding 9x9.
Boards are generated on the fly, so you will never run out.
■ A new puzzle every day
One board a day, the same for every player in the world.
Your clear time and your streak are recorded, so it is easy to make it a habit.
■ A hint when you are stuck
When nothing else works, Reimu will show you the next move.
No need to stare at the board forever.
■ Collect the characters
Clearing stages earns you omikuji points.
Draw an omikuji and add a new character to place on the board. 17 in all.
■ Pick up where you left off
Stop in the middle and your board is waiting when you come back.
Perfect for a few minutes on the train or before bed.
