The Games
Games that are actually instruments
Every one of these measures something you probably think you already understand. Brass is you, patina is the machine. Everything runs in your browser — no server, no inference calls.
Static× 4
odds and information, before anything moves
Blackjack Trainer
Basic strategy and true-count drilling. Every deviation you make from the chart is priced — and the coach tells you.
Tokenizer Golf
You price LLM calls in tokens but estimate them in characters. Guess counts, cut prompts under par, watch two schemes disagree.
Next-Token Duel
Predict the next token of a held-out passage, scored in bits of surprisal. Perplexity stops being an abstraction about four tokens in.
Kelly Run
Twenty flips of a biased coin. The bias is never told to you — infer it from outcomes while you bet against a full-Kelly bot.
Engine× 3
the machinery, with the covers off
Descent Golf
Four loss surfaces, each a specific pathology. Pick an optimizer and a learning rate, reach the target under par.
Connect Four
The game is the excuse. Node counts, per-column evaluations, and what alpha-beta pruning actually saves you.
Entropy Wordle
The usual game, priced in bits. Every guess shows how much information you extracted — and what the optimal guess would have gotten.
Ledger× 1
the truth, written down before you asked
Arcade× 1
pure reflex, zero theory
In the works× 2
Context Window Tetris
Blocks fall — documents, chat history, tool outputs. Summarize, chunk, and evict to prevent context overflow.
Prompt Telephone
A prompt transforms through multiple voices and models. Guess the original from the final output.
