Gem Sorter
A belt-sorting **throughput** game. Gems ride the conveyor toward the chute; the **front gem** is live. **Tap the colour-matching bin** to sort it and the queue shifts forward. New gems keep arriving — sort fast, because if the belt fills past capacity it **jams** and the line's over. A tap on the **wrong-colour** bin is a misfire (three and you're out). More colours and a faster belt arrive the longer you last. Chase your best haul.
Gem Sudoku
A **6×6 Sudoku** played with gems. Fill the grid so every **row**, every **column**, and every **2×3 region** holds all six gems. **Tap an empty cell**, then **tap a gem** from the palette: the right gem locks in; a **wrong gem costs a life**. Solve the grid to polish the set. 10 puzzles peel back from 24 clues down to 13.
Pipe Works
A **rotate-the-pipes** puzzle. A boiler line is a grid of fixed steam-pipe segments, scrambled by rotation. **Tap a segment to turn it 90° clockwise.** Steam enters at the glowing **inlet valve** and flows between any two segments whose connectors meet. **Seal the whole network** — every segment fed from the source, with **no open ends** — before your **wrench turns** run out. 10 lines grow from 3×3 up to 6×6.
