Forged for the Browser

LK Forge is a free collection of browser games and tools — six games plus a full browser toolkit — everything runs instantly with no download and no sign-up. The strategy games use minimax, alpha-beta pruning, and expectimax (the same algorithms behind competitive chess engines). Tools cover word, developer, network, time, weather, space, and earth-science tasks. Nothing you enter is uploaded — your text, files and data stay in your browser.

How the AI Works

The games here use classical AI algorithms, not large language models or chatbots. AI Tic Tac Toe uses minimax with alpha-beta pruning — a game-tree search that evaluates every possible board position; Hard mode is provably unbeatable. AI 2048 uses expectimax search to average over random tile spawns and find the statistically best play. Color Lines uses breadth-first search to find the optimal marble path.

AI Sudoku generates every puzzle with a guaranteed unique solution. The hint engine applies naked-single and hidden-single deductions and explains each step. Brain Puzzles uses a real BFS solver to power hints and par counts for its sliding-tile and block-puzzle modes. Word tools draw on dictionaries and letter-frequency analysis; developer, network, and time tools run their logic entirely client-side.

Whether you are playing or working, the intelligence is woven into the core experience — fast, private, and free.
