Tetris has run on more platforms than almost any other game, and the reason is simple: the loop of guiding a falling shape into the gap it fits, then watching a full row disappear, has never needed an upgrade. The official app pulls that loop behind a store install and a permissions prompt. We wanted the same itch scratched the second the page opens, so we built Stackwave, a free falling-block puzzle that runs right here, with no download and no signup.
Play Stackwave now
Tap to start. Use the on-screen pad on a phone or the arrow keys on a keyboard, and best played with sound on.
How to play
Guide each falling piece into the row you are building. On touch, use the arrows to slide left and right, the rotate button to spin the piece, Drop to nudge it down a row at a time, and Slam to send it straight to the floor. On a keyboard, the arrow keys move and soft-drop, the up arrow rotates, and space bar slams the piece down.
Clear a horizontal row and it disappears, dropping everything above it down a level. Clear several rows at once, or clear rows back to back without a miss, and the score climbs faster. The board resets to the same piece order for everyone on a given day, so your run is a fair comparison against yesterday’s best, not the luck of a random shuffle. Your top score and day streak are saved right on your device. Nothing leaves your browser.
How it compares to Tetris
Stackwave keeps the one thing that makes the genre worth playing: a falling piece, a row to complete, and a fall speed that keeps climbing until you misjudge a drop. Rounds end in a minute or two, a restart is one tap, and the daily seed gives you a reason to open the page again tomorrow.
We deliberately left out the rest. There is no marathon mode, no versus multiplayer, no unlockable themes, and no account to sign into. Tetris, in its official mobile release, ships all of that: ranked online matches, a battle royale mode, daily missions, and cosmetic packs sold as in-app purchases, all wrapped around the same core loop we built here in a single page. That depth is exactly why the official app is worth installing if the loop hooks you.
So think of Stackwave as the fast lane. If you want a clean stacking puzzle you can open in a tab during a break, it lives on this page for free. If you want ranked ladders, seasonal events, and a piece counter that tracks your lifetime stats, the real Tetris app is the better long-term home.

Frequently asked questions
Can I play Tetris in a browser?
Not the official version. N3TWORK distributes the licensed Tetris® app for Android and iOS, and it is not offered as a browser game. Stackwave, the game on this page, is our own falling-block puzzle built for the browser, with the same drop-and-clear loop and none of the install steps.
Is this the real Tetris?
No. Stackwave is an original game we built, inspired by the general falling-block puzzle genre that Tetris made famous. Its shapes, colors, sounds, and code are all our own, and it is not affiliated with, endorsed by, or connected to N3TWORK, the Tetris Company, or any Tetris trademark holder.
Does it work offline?
Yes. The entire game is a single page with no external requests, so once it has loaded it keeps working even if your connection drops. Your best score and streak are stored locally in your browser and never sent anywhere.
Is Stackwave free?
Completely. There are no ads, no accounts, and nothing to buy. The only thing that changes day to day is the piece order, which resets at midnight local time.
Why is the board a different size than official Tetris?
We use a narrower well tuned for a quick browser session on a phone screen, rather than a direct copy of any specific release’s dimensions. The core mechanic, rotate and slide a falling piece to complete a row, plays the same either way.
