Jewel Block Puzzle High Score Strategy:

1. **Start with Corners**: Begin by filling from the four corners with small blocks, always leaving the center empty. 2. **Leave Large Spaces**: Always reserve space for a 3x3 large square or a long rectangular shape to avoid getting stuck. 3. **Clear Multiple Lines at Once**: Save up full rows and columns, and when you get the chance, clear 2 or more lines at once for Combos and a huge score boost!
