Block Burst

You earn 2 points per block placed. Clearing lines gives bonus points, and consecutive clears boost those bonuses with a combo multiplier.

Reroll replaces only the unused pieces in your current hand. You start with one charge and gain more as your score increases.

The run ends when none of the three pieces in your hand can be placed anywhere on the board.

You start with 1 reroll and earn another every 700 points, up to a maximum of 3 held at once. Because charges are scarce, save reroll for moments when truly nothing fits — not just for a slightly better hand.

Reroll only replaces your unused pieces, so place anything that fits cleanly first — especially moves that clear lines. Burn the reroll when your hand is full of awkward shapes that block the board, ideally right before a big cascade setup.

Each placed block is 2 pts. Clears pay a base of 40 / 120 / 260 / 420 for 1 / 2 / 3 / 4+ lines, times (1 + 0.25 × combo chain), capped at ×2.5. The chain grows only on consecutive clearing placements — any placement with no clear resets it to 0.

Fresh hands are generated until at least one piece fits (up to 180 tries, then a forced single-dot fallback), so a new hand is never dead on arrival. No saved best — each 8×8 run stands alone. Solo only. Free in the browser, drag pieces, no download.

Pieces never rotate — place them as drawn. Your hand is always 3. Shape difficulty scales with score: all easy under 1000; 70% easy / 30% medium until 3000; then 45% easy / 35% medium / 20% hard (5-cell lines, plus, U, P, L). Colors are cosmetic; occupancy fills the 8×8. Rows and columns both clear.

Clearing lines on back-to-back placements builds a combo chain: each consecutive line clear multiplies the line's base score (40/120/260/420 for 1–4 lines) by 1 + 0.25 × chain, capped at ×2.5. Placing a piece without clearing a line resets the chain to zero, and clearing several lines with one piece scores the bigger base on top of the bonus blocks.
