Block Blast
Three pieces land in your tray. You drag each one onto an 8×8 grid, and any row or column you fill completely disappears. That's the whole game — but the pressure of always holding exactly three shapes, with no idea what comes next, is what makes it addictive.

Competitive vs. Fun: pick your rules
🏆 Competitive is the real test — no hints, no swaps. The moment none of your three pieces fit anywhere on the board, the run ends and your score locks in against your personal best.
🎉 Fun keeps the same grid but removes the dead ends: tap for a hint, swap your whole tray for free as often as you want, or trigger a board rescue when things get tight. It's the version built for a five-year-old who wants to keep playing without hitting a wall.
Tips for a higher score
- Leave at least one full empty row or column open at all times — it's your escape hatch for oddly shaped pieces.
- Clear from the edges of the grid inward rather than the center, so you don't box yourself into a checkerboard of isolated gaps.
- In Competitive mode, think one tray ahead — decide where the third piece will go before you place the first.
Frequently Asked Questions
What's the difference between Fun mode and Competitive mode?
Competitive plays by classic block-puzzle rules with no help. Fun mode adds on-demand hints, unlimited piece swaps, and a board-rescue option, so a bad tray never has to end the round for a younger player.
Why does the game end even though the board isn't full?
You're always holding three pieces at once. In Competitive mode, the round ends the instant none of the three can legally fit anywhere on the grid — a high score comes from leaving room for awkward shapes, not just filling space quickly.
What if I get stuck with three pieces that don't fit?
In Fun mode, the Swap button hands you three brand-new pieces for free. Competitive mode has no swap, so reading the board ahead of time is the only way to avoid getting boxed in.
