Arkadium Sudoku is a fun online version of the popular offline number-placement game available for a single player to enjoy across Easy, Medium, Hard and Expert modes. The game challenges the player's deductive reasoning skills on a traditional 9x9 grid that contains blank and numbered spaces across nine 3x3 subgrids.
The prefilled numbers provide the player with clues about the possible sequence of numbers they can use to complete the puzzle. Their goal is to fill the blank spaces with the remaining numbers from 1 through 9 in each subgrid. They must complete this process without ever repeating numbers within subgrids or a subgrid's pattern across the grid.
Arkadium Sudoku offers many of the same features that an online player would expect when enjoying Sudoku. They can erase a number. They can place notes about possible numbers that they might use in a space or the whole puzzle.
The game offers extra special features as well. The player can set it to reveal errors in their logic. On the main menu, they can choose to solve a cell with a tool marked with a magnifier icon. They can save their game at any time or print it to enjoy it offline in paper format.
