Three small things built end to end with AI tools, to learn what the tools can do and where they fail. Feel free to try them out, they are free.

MatematikVerdener
A Danish maths trainer for schoolchildren, grades 1 to 9. Six worlds (supermarket, kitchen, sport, building, banking, personal finance), 21 topics, 468 exercise types. Follows the Danish national curriculum (Forenklede Fælles Mål). Adaptive, no accounts, no tracking. In Danish.

Petal Blast
A block puzzle in pastels. Drag shapes onto the grid and fill a line to clear it. Clearing lines back to back builds a streak multiplier, and golden pieces double a clear. Two modes: Normal 8×8, or Mega 9×9 that also clears 3×3 boxes. Shared weekly and all-time high scores.

Twenty
The 20-number challenge. Twenty ranked slots, random numbers from 1 to 1000. Drag each one into place and keep the whole list in ascending order. One number with nowhere to go ends the run. Every placement pays more than the last, so the deeper the run, the higher the score. Shared weekly and all-time high scores.
