About this game

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.
