Costs prestige pointsprestige system
Prestige is how SudoSquad identifies the world's top Sudoku players. It's earned from every competitive solve — speed, accuracy, difficulty, mode. Nothing else.
Each difficulty has a par time — the expected solve for a competent player. Beat par and your score climbs above the base. Miss it and it drops, but never below 20% of the base. Completing the puzzle adds a bonus on top.
| Difficulty | Par | At par | Max |
|---|---|---|---|
| Easy | 5 min | 150 | 450 |
| Medium | 10 min | 300 | 900 |
| Hard | 20 min | 600 | 2,000 |
| Expert | 35 min | 1,050 | 3,850 |
| Diabolical | 60 min | 1,650 | 6,600 |

multiplicative penalties
Prestige gain slows as your total rises: new players climb fast, elite players earn every point. This is to make sure SOVEREIGN is truly earned.
The global Sudoku ranking. Lifetime prestige — it never resets.
Sovereign prestige requires 250,000+ pts which is equivalent to ~14,000 competitive games. That is legend-ary.
