Solvers and random generators for puzzles and games. The Sudoku solver takes any valid 9x9 grid and fills in the solution instantly. The random number generator produces one or more whole numbers within a range, with or without duplicates. The dice roller supports standard NdM notation — roll 2d6, 4d20 or 3d6+2 and see each individual die alongside the total. The random name picker draws a name from a list you provide, or shuffles the entire list into a random order. Each tool runs in your browser with nothing sent to a server. The random tools use the browser's built-in cryptographic random number generator rather than a weaker alternative, so the results are as fair as software randomness allows.
