A digital reasoning game full of wisdom and challenge! Here, you will become a clever explorer and fill in the mysterious grid by dragging and dropping rocks (representing different numbers). Note, however, that the rule here is not simple - no number can be repeated in any row, column, or 3 × 3 square area.
Observation and reasoning: At the beginning of the game, a portion of the numbers in the grid will already be given. Your task is to use these known numbers, combined with the reasoning skills of Sudoku, to deduce the location of the missing numbers.
Drag and Drop Rock: Click and select the number (rock) you want to place, then drag it to a blank spot in the grid. If placed correctly, the number will stay there; If it is misplaced, it will return to the area you selected.
Make use of small stone markers: To help you better track the guessing and reasoning process, you can use smaller stones to mark locations that you think might be correct or to rule out certain impossible choices. In this way, you can see the reasoning process more clearly at each step.
