Test your observation skills to the ultimate with this easy yet challenging number filling puzzle! This game aims to make your eyes sharper, train your attention to details, and provide players with a simple and brain boosting gaming experience. Each grid is waiting for you to analyze, judge, and fill in the correct numbers through careful observation and precise operation.
The game control is very simple and user-friendly. Click on any blank cell on the grid, and then select the corresponding number from the on-screen keyboard to complete the filling.
