Glyph Grid

A retro "thinking person's Tetris". Place increasingly complex Tetris-like shapes in a playing area. Get coins for placing and clearing, spend coins to continue in tough situations. The difference to similar games is the randomly generated shapes that get more and more difficult, requiring you to spend hard-earned coins to blast them away. Now includes a unique "mirror mode". Don't rotate, mirror. For computers and mobile devices.

Wortwelt (German)

Re-interpretation of crosswords in the age of AI. You get all empty words, and no description of what to enter. Instead you get an overall goal like "Find words for plants", and have to creatively find the most exotic words that fulfill the goal. An LLM will judge your effort and award points.

Implementation Details

Originally built with Replit and ChatGPT 4. Later ported to a SPA UI with ChatGPT o1. Calls ChatGPT as "Oracle" that evaluates your play. Wonderful piano background music by Stability.ai's Stable Audio

Please note: this app calls ChatGPT, and every call costs me a tiny bit of money. Therefore I had to add a simple login mechanism, and a user and transaction limit. Drop me a mail if you need a user or more queries.

Storytellers

Take turns with an AI to write a story. Write as many sentences as you want. At any time ask ChatGPT o1 or Deepseek R1 to continue your story with the next sentence. You can also create chapters and give every chapter a summary of what to tell in this chapter.

Originally built with Replit and ChatGPT 4. Used Llama3, Mistral and ChatGPT4 as LLMs. Later reduced to ChatGPT 4o and Deepseek R1, and reworked the UI with help of ChatGPT o1.
