The goal of Check3 is to strategically place three check marks (✔) in every row and every column without violating the game's placement rules:

• Check marks cannot be placed right next to or directly above/below each other.
• If a spot cannot contain a check mark, place a cross (✖) to help track available spaces.
• Use logical deduction and eliminate impossible spots to gradually complete the grid.

Want to master Check3? Follow these expert tips:

• Start by placing crosses where check marks are not allowed to spot open spaces faster.
• Look for rows or columns that already have two check marks—this will limit the possible locations for the third one.
• Double-check before placing a check—mistakes can make solving the puzzle harder!
• Break down the grid into smaller sections and solve each logically.
