How Does the Block Blast Scoring System Work?

What Is the BlockBlastPlay Browser Scoring Formula?

Score gained on a single placement breaks into three parts:

Score gained on a placement =
  piece-cell points
  + line-clear points
  + combo bonus

piece-cell points = number of occupied cells in the placed piece
line-clear points = 80 × number of rows/columns cleared
combo bonus = 0 on the first clearing placement in a chain;
              combo × 50 from the second consecutive clearing placement onward

On a placement that clears no line: piece-cell points still apply, there are no line-clear points, the combo counter resets to zero, and there is no combo bonus. Every figure in this formula was reverified directly against the current BlockBlastPlay production source before publishing, and is demonstrated below with executed test cases rather than asserted on its own.

How Many Points Do You Get for Placing a Piece?

One point per occupied cell in the piece, awarded the instant it’s placed — before any line-clear check happens. A 1×1 piece is worth 1 point on placement; a 5-cell piece is worth 5 points on placement, regardless of where it lands or whether it clears anything. This is separate from, and added to, any line-clear points earned on the same placement.

How Many Points Is a Row or Column Clear Worth?

80 points per completed row or column, cleared in the same placement. A single completed row is worth 80 points; a single completed column is also worth 80 points. If one placement completes a row and a column at the same time, that counts as 2 cleared lines for scoring purposes — 160 points — not a special combined bonus. There is no separate “cross clear” bonus in the verified source; it’s the same 80-per-line rule counted twice.

How Are Multiple Lines Scored?

Linearly — 80 points × however many rows/columns are cleared by that one placement. There is no escalating lookup table for 1, 2, 3, 4, 5, or 6+ lines, and no separate full-board bonus in the current BlockBlastPlay browser scoring code. Two rows cleared by one placement is 160 points, exactly the same as one row plus one column; there is nothing that makes a larger simultaneous clear worth disproportionately more per line than a smaller one. Any combo bonus from consecutive clearing placements (below) is added on top of this linear total — it is not part of a bigger per-line-count table.

How Does the Combo Bonus Work?

Every clearing placement increments a single combo counter by 1; any placement that clears nothing resets that counter to 0. The bonus itself only applies from the second consecutive clearing placement onward: the first clearing placement in a chain scores combo=1 but a bonus of 0. The second consecutive clearing placement scores combo=2 and a bonus of 100 (combo × 50). The third consecutive clearing placement scores combo=3 and a bonus of 150. The combo value used in the bonus calculation is always the value after incrementing for the current placement, not before.

Breaking the chain — placing a piece that clears no line — resets the counter to 0 immediately. The next clearing placement after a reset starts the chain over at combo=1 (bonus 0), exactly as if no prior chain had happened.

Is Combo a Multiplier?

No — not in this browser implementation. The combo bonus is added to the placement and line-clear points, not multiplied against them. A second consecutive clearing placement that clears one line scores 80 (line-clear points) + 100 (combo bonus) = 180 on top of its placement points — it does not score double the base value, and there is no “2× multiplier,” “3× multiplier,” or general score multiplier anywhere in the verified code. If a search for “combo multiplier” brought you here: for the BlockBlastPlay browser build specifically, the mechanic is an additive bonus, not a multiplicative one.

Is There a Separate Streak Bonus?

No. The current BlockBlastPlay browser build has exactly one scoring-state counter — combo — not two. Some casual guides use “streak” descriptively to mean the same thing as consecutive clearing placements, which is a reasonable plain-language description of how combo behaves, but there is no second, independently coded “streak” mechanic running alongside combo in this build. Anywhere this page uses the word “consecutive,” it is describing the single combo counter above, not a separate system.

Is There a Full-Board or Perfect-Clear Bonus?

No. The current production scoring code was directly checked for a full-board clear, all-clear, perfect-clear, or board-empty bonus, and for any lookup value resembling 360 points — none exists. Clearing every line on a completely full board scores exactly the same way as any other clear: 80 points per line, plus any applicable combo bonus. There is no separate bonus on top of that for having cleared the entire board at once.

Does the Official Block Blast App Use the Same Formula?

Not established. The official App Store listing for Hungry Studio’s Block Blast mentions combos only in passing — “Chase Combos: Plan your moves to unlock massive points and extend your endless high score run” — with no scoring formula, point values, or multiplier rule given. The official materials reviewed for this page do not provide enough detail to establish that Hungry Studio’s mobile app uses this same scoring formula. Everything above — 1 point per placed cell, 80 points per cleared line, the additive combo bonus — describes BlockBlastPlay’s own browser implementation, verified directly from its own source code, not the official app.

Worked Scoring Examples

Every example below traces to an executed, predefined test case against the production scoring logic — not arithmetic invented after the fact.

Example 1 — No Clear

Placing a 1×5 piece (5 occupied cells) into open space, with no line cleared:

Piece cells	5
Placement points	5
Line-clear points	0
Combo bonus	0
Total gained	5

Example 2 — First One-Line Clear

A single 1×1 piece placed into the last open cell of a row, with combo at 0 beforehand (no prior clearing placement):

Placement points	1
Line-clear points (1 line × 80)	80
Combo after	1
Combo bonus (first clear = 0)	0
Total gained	81

Example 3 — Simultaneous Row + Column

A single 1×1 piece placed at the one cell shared by an otherwise-complete row and an otherwise-complete column, with combo at 0 beforehand:

Placement points	1
Lines cleared	2 (1 row + 1 column)
Line-clear points (2 × 80)	160
Combo after	1
Combo bonus (first clear = 0)	0
Total gained	161

Example 4 — Two Consecutive Clearing Placements

First clearing placement (combo 0→1): 1 placement point + 80 line-clear points + 0 combo bonus = 81. Second consecutive clearing placement immediately after (combo 1→2): 1 placement point + 80 line-clear points + 100 combo bonus (combo 2 × 50) = 181. That 100-point combo bonus is added on top of the base total — it is not a “2× multiplier” on the 81 from the first clear.

Placement 1 total (combo→1)	81
Placement 2 total (combo→2)	181 (80 base + 100 additive combo bonus)

Example 5 — Combo Reset

Clear → combo starts at 1. Next placement clears nothing → combo resets to 0, no line-clear points, no combo bonus (only the 1 placement point for that piece applies). The following clearing placement after that starts the chain over: combo becomes 1 again, bonus 0 — not a continuation of the earlier chain.

Placement A: clears a line	combo → 1, bonus 0
Placement B: clears nothing	combo → 0, only placement points
Placement C: clears a line	combo → 1 again, bonus 0 (chain restarted)
