Chess

Mon, 01 Jan 0001 00:00:00 +0000

About

A Go server that exposes chess as a REST API, with Stockfish behind it for move validation and computer play. The server owns the rules; clients own nothing but the display, which is why three very different ones talk to the same endpoints.

Games are anonymous by default. An account is optional and only changes who the game is recorded against.

Modes: Human vs computer, human vs human, computer vs computer.
Engine: Stockfish, skill level 0–20, per-move search budget 100–10000 ms.
Positions: Any legal FEN — puzzles, endgames, mid-game starts.
Export: PGN move list plus the current FEN, straight to the clipboard.
Clients: Web UI, terminal CLI, and the same CLI compiled to WebAssembly.

Play

Drag-free click-to-move, last-move highlighting, undo, live server and storage indicators, and a move list that copies out as PGN.

Lixen Rings

Mon, 01 Jan 0001 00:00:00 +0000

Gameplay

8 concentric rotatable rings, each with a single notch, from a random start position.
Align all eight notches onto one vertical line to solve the board.
The twist: rotating a ring drags both of its neighbours along at half speed, so every correction is also a disturbance — the puzzle is working out which ring to move last.

How to Play

Select: Tap to cycle rings (1→8→1), or drag vertically to jump.
Rotate: Drag horizontally to rotate. Adjacent rings move at half speed.
Solve: Align all 8 notches to the vertical line.

Mid-run — ring 4 selected, notches scattered

Solved — all eight notches on one line

Demo

A full run — the goal screen, a new board, manual ring rotations, then the built-in solver finishing it, and back to the goal screen.

Vi-Fighter

Mon, 01 Jan 0001 00:00:00 +0000

About

A terminal action game on a custom Entity-Component-System engine. Go standard library only — no third-party dependencies, no CGO.

Movement, targeting and editing all run through vi motions: hjkl, w/b/e, f/t, counts, operators, registers and macros, across normal, insert, visual, search and command modes. Keyboard, mouse, or both.

Enemies adapt during the run in some map setups. Species parameters mutate against past-generation fitness, and spawn probability shifts toward routes that score.
