Blockstellar
Drag · Blast · Combo
Drop glowing gem blocks onto an 8×8 board. Fill a row or a column and it blasts into stardust. Chain the clears back to back and the announcer starts shouting.
Free to play. One optional upgrade. No subscription.

A1 — The loop
Three pieces. Eight by eight. No timer.
You are dealt three shapes at a time and you place them wherever they fit. Nothing falls, nothing rushes you, and the run only ends when none of your three pieces has a home. Every board is a puzzle you built yourself.
Drag anywhere it fits
No gravity and no clock. The dealer guarantees at least one of your three pieces has a home whenever that is still possible — tense, never cheap.
Fill a line, blast it
Complete a row or column and it detonates into stardust. Clear several at once and the whole board shakes.
Combo, then keep going
Back-to-back clears build a multiplier and pull increasingly unhinged callouts from the announcer. Break the chain and it resets.
D4 — Two ways to play
Chase a number, or clear 200 levels.
Survive your own board
One score, no ceiling. The edges darken as space runs out. A Fuse Core lights up on the board and counts down — clear its line for a fat bonus, or watch it blow and take a Nova Star with it. Run out of stars and the run is over.
200 levels, 10 chapters
Free the gems trapped in the grid before your piece budget runs out. Finish with room to spare for three stars. Ten themed chapters, each harder than the last.
Pick a callsign and every Endless run posts to the global leaderboard — a weekly board that resets every Monday, and an all-time board for the run of your life. Prefer to play alone? Skip the callsign and it never comes up again.
Coins buy block skins. Runs earn ranks. Daily missions and a streak keep the flame lit. Eighteen achievements, twenty ranks, and your five best runs.
H8 — The upgrade
One purchase. That is the whole shop.
Blockstellar is free, and the free version is the whole game — every level, every mode, nothing locked behind a wall. It pays for itself with ads you choose to watch and an occasional one you do not.
✦ Blockstellar Deluxe
Removes every ad, unlocks the four premium block skins, doubles the coins from each run, and gives you two Nova Stars instead of one — twice the cushion against a Fuse Core. Anything a free player can earn by watching an ad, Deluxe simply grants — you never come out behind for having paid.
