Hold 81
How to Play
81 Holds is a hold-and-spin style game played on a 9×9 grid divided into nine 3×3 sub-grids. At the start, only the first sub-grid is active and you have 3 respins.
On each spin, all empty cells in the active grids spin independently. If a cell lands a winning value, that value is locked in place and the number of respins is reset to 3. New sub-grids unlock automatically when two-thirds of the active cells are filled.
The game ends when no respins remain or all 81 cells are filled.
Each spin costs 100 credits, and the game has an RTP of 96%.
