Grid Blast Wiki

Scoring & combos

Every placement counts — but chained line clears are where runs explode.

Placement points

Each cell you place awards 10 points. A three-cell L-shape therefore earns 30 points on placement, before any line clears.

Line clear bonus

When one or more full rows or columns clear in the same turn:

Base: 100 points per cleared line (row or column counts separately).
Multi-line: Each additional line in the same turn adds +50 on top of the per-line base (e.g. 2 lines = 100 + 50 = 250 before streak).

Example line clears

1 line → 100 pts (+ placement)
2 lines → 250 pts (+ placement)
3 lines → 400 pts (+ placement)

Combo streak multiplier

Clear at least one line on consecutive placements to build a streak. If a placement does not clear any line, the streak resets to zero.

Streak 1 (first clear in a chain) → ×1.0 multiplier on line-clear points
Streak 2 → ×1.5
Streak 3 → ×2.0
Streak 4+ → +0.5 per streak level (×2.5, ×3.0, …)

The HUD shows the active streak label (e.g. ×2.0 STREAK) after back-to-back clears.

Star gem bonus

Empty cells can hold golden ★ star gems. When a clearing line passes through a star cell, you earn +150 points per star in that clear. After a line clear, up to two new stars spawn on random empty cells.

High score

Your personal best is stored in local browser storage and shown on the menu and in-game HUD. Portal leaderboards depend on the distributor integration.
