About
Ninjas is a logic game where you put a number of ninjas in every row and column while making sure none of them touch. It is also known as "shapeless Star Battle".
How to play
- Tap an open cell to cycle through cross and ninja. Crosses are visual markers only.
- Place one ninja in each row and column. In Hard and Very Hard, place two.
- Ninjas cannot touch, even diagonally.
- The board is solved when all ninjas are placed and every rule is satisfied.
Tips
- If a ninja must be in one of two neighboring cells, look for cells that would touch either position. Those cells must be empty.
- In Hard and Very Hard, consider which pairs can fit without touching. A cell shared by every possible pair must contain a ninja.
