Best score ranks your best single puzzle: 10 points per digit times the level multiplier (×1 Easy up to ×4 Expert), plus a solve bonus, a bonus for every second under par time and a bonus for zero mistakes. Puzzles solved counts every validated solve.
Each run opens a server session when it starts. When it ends, the server checks how long it took, how many moves it needed and what score the rules allow, so sped-up or invented results never reach the board.
Sign in to your free CPSCount account and play Sudoku. Finished runs are submitted automatically and also earn XP and coins. Guests can play every mode too; their bests simply stay in the browser.
Every digit you place correctly yourself is worth 10 points times the level multiplier, and each cell pays only once: erasing a digit and typing it again earns nothing extra, and digits revealed by a hint score zero. Finishing the grid adds a solve bonus of 300 × multiplier, 1 × multiplier for every second under par (4 minutes on Easy, 7 on Medium, 11 on Hard, 15 on Expert) and 200 × multiplier for a flawless solve. Example: an Expert grid with 54 empty cells, solved without hints or mistakes in exactly 10 minutes, scores 2,160 + 1,200 + 1,200 + 800 = 5,360.
Each puzzle allows three mistakes; the third wrong digit ends the run. A lost run keeps the points of the digits you got right, but it gets no bonuses and does not count as solved. You also have three hints per puzzle, and they cost you only the points of the cells they fill. If two players share the same best score, the faster time (shown next to the score) ranks higher; on Puzzles solved, whoever reached the count first stays ahead.
Difficulty matters more than speed: because the multiplier covers every part of the score, any finished Medium, Hard or Expert grid beats the best possible Easy result. Pencil in candidates with Notes (N) instead of guessing, since a single mistake already costs the flawless bonus. Keys 1–9, the arrows, Z (undo) and H (hint) keep your hands on the keyboard, and the game pauses itself when you switch tabs. An unfinished puzzle is saved in your browser for each level, so you can pick it up later with Continue. Warm up on the Sudoku page, then try another logic challenge in Minesweeper or see who leads the Memory Match leaderboard.
