Scacelith
Skip the top-down board and sit at the chess table: a first-person chess simulator with built-in Stockfish 19 and a robot coach.
Scacelith is a first-person chess simulator: instead of looking down at a board from above, you play as if you were really sitting at the chess table, with the pieces, the board, and the hall right in front of you. Your opponent is the built-in Stockfish 19, adjustable by strength and time control, and you can set your own Elo rating to track your level. Beyond normal games, it has a robot coach: the coach sets problems at your level, explains what you got wrong, and points out the bad move on the board with its own hand, with 128 tactics, mating, and endgame exercises to go with it. You can also import your own games or a PGN for analysis with spoken commentary, play friends online, play two players on one computer, or watch two Stockfish engines play each other. The visuals and sound have a special twist: the whole hall, the pieces, the robots, and the sound effects use no ready-made assets at all — everything is computed by code, from an in-house OpenGL engine, with graphics quality adjustable from very modest to very high depending on your graphics card. The game is free and open source; download, unpack, and play, no installation needed. A few things to watch: it needs a graphics card that supports OpenGL 4.6, and supports Windows, Linux, and Apple Silicon Macs (the Mac build is still experimental and may run slower). None of the three system builds is properly signed yet, so Windows will show a SmartScreen warning and Macs need a one-time manual approval in System Settings. The good news is it is still being updated: version 1.0.4 arrived on 24 October 2026, mainly translation improvements, after 1.0.2 and 1.0.3 landed within the previous week.
