The whole game, explained from scratch. No prior block-stacker experience needed.
Bloblokin is a falling-block puzzle game. Gooey blobs drop into a tall container called the Well; you slide and rotate each one as it falls, and when a horizontal row is completely filled it clears and everything above it settles down. Fill rows faster than the stack rises and you keep playing. Let the stack reach the top and the game ends.
That much is familiar if you have played any block stacker. What makes Bloblokin its own game is what happens to the lines you clear in versus modes: they turn into Sludge rows that rise in your opponent's Well. Clearing is not just survival, it is your attack.
The Well is 10 columns wide and 20 rows tall, with 20 more rows of hidden space above the visible area so a blob always has room to spawn and rotate. That buffer is working room, not extra playing field: you overflow the moment a new blob has nowhere to spawn, or a blob comes to rest entirely above the visible 20 rows, or rising Sludge pushes part of your stack out of the top. Any of the three ends the run.
There are seven blob shapes, each four cells: a straight Noodle, a square Chunk, a three-plus-one Perch, the mirrored Squiggle and Ziggle, and the mirrored Hook and Crook. They arrive in a shuffled bag: every set of seven contains each shape exactly once, so you will never wait more than twelve blobs for the piece you need, and you can plan around what has already appeared.
The next 5 blobs are always visible in the queue. Use them: good players are placing the current blob while deciding where the next two go.
A blob does not lock the instant it lands. You get 0.5s of settle time to keep sliding and rotating it, and each successful move restarts that timer, up to 15 times, after which it locks regardless. That cap is what stops a blob being held indefinitely at high speed, and it is why late shuffling is a habit worth breaking.
Fill all 10 cells of a row and it clears. You can clear up to four rows at once, and bigger clears are worth disproportionately more, both in points and, in versus, in damage:
| Clear | Rows | Points (level 1) | Sludge sent |
|---|---|---|---|
| Single | 1 | 100 | 0 |
| Double | 2 | 300 | 1 |
| Triple | 3 | 500 | 2 |
| Quad | 4 | 800 | 4 |
A four-row Quad is worth 800 points against 400 for four separate singles, and sends 4 rows where four singles send 0. Learning to build for Quads is the single biggest scoring change a new player can make.
The Pocket holds one blob for later. Swap the falling blob into it and you get back whatever was there before (or the next blob, if the Pocket was empty). You may use it once per blob: it refreshes after the next lock, so it cannot be used to cycle endlessly through the queue.
In solo modes, a run ends when you complete the objective (150 lines in Marathon, 40 in Sprint, and so on) or when you overflow. In versus modes the last player whose Well has not overflowed wins. Duels add sudden death at 3:00: both Wells take a rising Sludge row every 10s and the level floor climbs, so a stalemate always resolves. Rumbles get a finale at 5:00 instead, a rising Sludge row for everyone still alive, with no gravity ramp.
