How to play
Drag a piece onto the board
Three pieces wait in the tray under the 8×8 board. Drag one onto the board and let go. Pieces never rotate, so look before you drop. Once all three are placed, a new set arrives.
Fill a row or a column
While you drag, the rows and columns your piece would complete light up. Drop it there and every full row and column clears at once.
Keep the combo going
Every move that clears a line raises your combo, and the combo multiplies the points of each clear. After a clear, the dots show you have 3 moves left to clear again; if none of them clears a line, the combo ends.
Clear many lines at once
Clear two lines with one move for Pop!, three for Boom!, four for Kaboom! and five or more for Blastoku! Points grow with the square of the lines you clear together, so one big clear beats several small ones.
Empty the board
Clear the last block on the board for Spotless! and a bonus of 300 points times your combo. When none of your three pieces fits anywhere, the run is over.
Tips & tricks
Plan around the next set
A new set only arrives once all three pieces are placed, so place the awkward piece while the board still has room for it.
Trust the dealer
At least one piece in every set fits on the board, pieces that finish a line show up often, and big pieces get rarer when the board is crowded.
Shuffle the tray
Stuck with pieces you can't use? Twice per run, the Shuffle button at the top of the game screen swaps your 3 pieces for a new set if you choose to watch an ad.
Take one move back
Dropped a piece in the wrong spot? Once per run, right after a move, the Undo button takes it back if you choose to watch an ad.
One more chance
When no space is left, you can watch an ad once per run to get 3 small pieces that fit and keep your score.
Play the daily board
Home has a daily board with the same first set for everyone that day. You get one try a day, and Home shows your score until the next board.
Leave whenever you like
Your run is saved after every move. Close the game, then tap Continue on Home to pick up where you left off.
FAQ
Is Blastoku free?
Yes. It is free to play and supported by ads. There are no in-app purchases and no paid content.
When will I see ads in Blastoku?
Never while you place pieces. A full-screen ad may appear between matches, when you tap Play again or Home after a game over: at most once every 3 matches, at least 2 minutes after any other full-screen ad and not in the first 2 minutes, after a short "Ad break" notice. Home and the game over screen show an ad card marked "Ad". Rewarded ads play only when you choose them.
Which rewards can I get from an ad in Blastoku?
Continue (3 small pieces that fit, once per run), Shuffle (a new set, twice per run), Undo (your last move back, once per run), 15 minutes with no ad breaks from the Pause screen, and steps toward the Neon block colors (3 ads, or a high score of 5,000). Each reward can be earned up to 5 times a day.
Can I play Blastoku without internet?
Yes. The whole game works offline. Ads, and with them the rewards, need a connection.
Where is my Blastoku progress saved?
Only on your device, after every move. It is not included in Android's cloud backup, though a direct transfer to a new phone on Android 12 or newer can carry it over. Uninstalling the game or clearing its storage deletes your runs and your scores.
Which phones can run Blastoku?
Android phones running Android 7.0 or newer. The game is in English.
What data does Blastoku collect?
We don't collect or receive your personal data. Google AdMob, which shows the ads, collects some device and usage data, such as your advertising ID and approximate location. Where the law requires it, you are asked for consent first. Read the privacy policy
