Glitched Lands is a map of coding and data missions. Every land has its own world and its own colour. You solve it on your own computer, in any language, and every answer you upload plays back as an animation.
No account needed for the first stage.
Code Christmas 2026Pine Square
The lights on the town tree blink by one odd rule. Predict them, outlast the Glitch, then make them draw a picture.
Press Start. The clock begins and you download your own input file. Nobody else has the same one.
Write the program on your own computer, in any language you like. There is nothing to install here.
Upload the answer file. It is checked at once and replayed step by step. A wrong answer stops exactly where it broke.
Every stage adds a rule and pays more points. Halfway up the Glitch breaks a rule you trusted. On the last stage you stop predicting and start deciding.

This is a real stage 4 plan from Lost Drones. Each drone flies the commands its player wrote, one tick at a time. Most make it home. Some don't.
The replay runs until the first thing that breaks and stops there. It shows you where, never the fix.
Every player gets different data for every stage, so nobody can copy an answer.
You alone, no AI tools. You promise it before you start, your source code goes up with every answer, and a run too fast for a person is moved to Duo. Ranked by points, then by time.
You and an AI, openly. Ranked by points, then by how few prompts you needed.
You pick one league per land, and it is locked with your first upload: an answer found in Duo cannot be sent again as Solo.
Code lands ask for a program that follows the rules. AI, ML and data lands ask you to learn from data. Every land is free.
