Eighteen builds, one obsession.

Each of these is my own build of a well-known mechanic, with its own generator and its own visual identity. The daily puzzles each have a solver that has to prove a puzzle is uniquely solvable before it's allowed to ship; Mint is a seeded daily score-attack instead. Below that: games you play against an AI opponent or against the clock, no daily challenge, just a local record.

Daily Puzzles

🧵 Topstitch a path puzzle Drag one seam through every numbered pin and every square of the fabric, in order. Play → ♛ Sovereign a region puzzle Seat one crown per row, column, and stained-glass pane. No two crowns may touch, even diagonally. Play → 🌗 Equinox a balance puzzle Split every row and column evenly between sun and moon, guided by equal and opposite clues. Play → 🔢 Tally a 6×6 mini sudoku One through six, once each, in every row, column, and 2×3 block. Play → 🧩 Calico a rectangle-dissection puzzle Cut the quilt into patches — each one sized and shaped to match exactly one clue. Play → 🪙 Mint a number-merging game Strike two matching coins together to mint a bigger one. Score-attack, not a fixed solution. Play →

Two more are on the way — a word-association game and a trivia word ladder. Those need a hand-written bank of clues rather than an algorithm, so they're taking a bit longer.

Play Against the House

✏️ Slate tic-tac-toe Chalk vs. chalkboard. Hard mode plays a mathematically perfect, unbeatable game. Play → 🔴 Cascade connect four Drop pieces into a wooden frame. Hard searches seven moves deep with alpha-beta pruning. Play → ⚫ Drafts checkers Ivory vs. ebony. Optional captures, forced multi-jumps once started, and kings that move both ways. Play → ⚪ Turncoat othello / reversi Green felt, lacquered discs, and a real 3D coin-flip when a line of pieces changes sides. Play → 🗝️ Cabinet memory match A curiosity cabinet of specimen tags. Play solo against the clock, or against a collector whose memory is only as good as the difficulty you set. Play → 🐑 Fold dots and boxes Sixteen pens, one fence rail at a time. Give away a third rail and the collector takes the pen — on Hard, they'll make you pay for every gift. Play → ♞ Study chess A real engine built from scratch — every rule, a genuine search a few moves deep, and an opponent that actually looks for tactics. Play →

Race the Clock

🏓 Rally a volley game Phosphor-green and first to eleven. The ball speeds up with every exchange, and where it lands on your paddle sets the angle. Play → 🧺 Bushel an orchard catch Catch the fruit, dodge the wormy ones. Everything falls faster the longer the basket stays out. Play →

Guess & Deduce

🕯️ Candle a word guess Guess the word one letter at a time. Every wrong letter burns the candle down a little further — no gallows here. Play → 🔎 Hunch twenty questions Think of something ordinary. The detective asks up to twenty yes-or-no questions and tries to name it. Play → 🖼️ Gallery a Guess Who deduction Twenty original portraits on the wall. Ask about a feature, eliminate who doesn't match, and name the sitter. Play →
