LK Forge

LK Forge: privacy-first browser tools & games, nothing to install, nothing uploaded. The game-AI engines and solvers run client-side in your browser, with no login.

What we work on

• Game-AI engines — minimax with alpha-beta pruning, MCTS, IDA*, expectiminimax, and negamax across chess, Go, Connect 4, checkers, othello, backgammon and more.
• Puzzle solvers — Sudoku, Rubik's Cube, mazes, word search, and others.
• LLM evaluation — we benchmark frontier models on game-playing ability. Read the study: ChatGPT vs Grok: Game-AI Benchmark

On Hugging Face

We publish the reproducible datasets behind our benchmarks here, each with a card linking back to the live solver and the full write-up on lkforge.com.

Solver & game-AI benchmark cluster:

• negamax-search-depth-scaling — Elo per ply of search for chess, Connect 4, checkers, othello
• minesweeper-solver-benchmark — win-rate by difficulty (Expert 36.2%)
• sudoku-solver-benchmark — backtracking vs MRV vs constraint propagation
• rubik-cube-solver-benchmark — min2phase solution length (~20.5 moves)
• sliding-puzzle-solver-benchmark — 8- & 15-puzzle IDA* length and nodes
• maze-solver-benchmark — BFS shortest-path effort by maze size
• tic-tac-toe-solver-benchmark — full minimax game-tree size (549,946 nodes)
• 2048-solver-benchmark — expectimax depth sweep (shipped engine reaches 2048 in 94% of 300 games)
• game-ai-vs-llm-benchmark — classical search vs a stochastic "LLM-sim" opponent (not a real LLM)

Every number is reproducible from the shipped, client-side engine, with no login.
