#game

A complete Texas Hold’em toolkit in one fast, fully-local API. Calculate win, tie and equity probabilities for your hole cards against any number of opponents (1–9) on any board — pre-flop, flop, turn or river — using a Monte Carlo simulation with adjustable accuracy. Evaluate the best five-card hand from any five to seven cards and get its rank and tiebreakers, or describe a hand in plain language. Cards use the familiar notation (As, Td, 9h, 2c) and every endpoint works by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for poker trainers and study tools, game developers, hand-history trackers and odds widgets.

Generate, solve and validate Sudoku puzzles through a fast, fully-local API. Create fresh puzzles at four difficulty levels (easy, medium, hard, expert), each guaranteed to have exactly one solution, returned as both an 81-character string and a 9x9 grid alongside the full solution. Solve any valid puzzle with a backtracking engine that also reports whether the solution is unique, and validate a grid to detect rule conflicts and completeness. Inputs accept an 81-character string (0 or . for blanks) or a 9x9 array, by GET or JSON POST. Pure server-side compute with no third-party upstream, so responses are instant and the service is always available. Ideal for puzzle apps and games, newspapers and printables, tutors and training-data generation.
