How to play Stacker
Watch the block slide
A new block glides left and right across the top of your tower at a steady rhythm. Track a full pass or two before acting - The beat is the whole game.
Drop it with one input
Press Space, click, or tap the screen to release the block. It falls straight down from wherever it was the instant you committed, so the timing of that single input is everything.
Keep every edge over the block below
Any part of the block that hangs past the one underneath gets sliced off and tumbles away. What remains becomes the new top of the tower - and the target for your next drop.
Land perfect drops for bonus points
Set the block down flush with the one below and nothing is trimmed: the tower keeps its full width and a bonus lands on your score. Chain perfects and the bonuses keep climbing.
Build until the tower gives out
Every floor you add slides a little faster than the last. The run ends when repeated slices whittle the block down to nothing - So protect your width like it is your health bar.
This independent browser adaptation uses the original game’s established title. It is not an official publisher release or an original ROM. Its artwork, tuning and controls may differ from other games with similar rules. Guest personal bests stay in this browser. Signed-in players can also save scores and play history to their private dashboard; there is no global leaderboard. Read about controls and local storage.

A late drop removes width from the next layer. Claw Crane turns that release-timing decision into a swinging claw, where a missed grab spends one of your tokens.
What Stacker is like to play
Stacker is one button and zero excuses. A block glides back and forth across the screen; you tap to drop it onto the stack below. Land it flush and your tower keeps its full width. Land it crooked and the overhang gets sliced clean off - Now your next block is narrower, your target smaller, and your palms noticeably sweatier. String perfect drops together and bonus points pile up, but one sloppy release can trim a proud tower down to a sliver in seconds. The blocks slide faster the higher you climb, so a run that begins as a lazy rhythm ends as a staring contest with physics. Our version answers to a tap, a click, or the space bar, and keeps your tallest build saved in this browser - One tower, your own hands, and a height to beat next time.

Where Stacker came from
Stacker descends from the arcade's timing machines - Cabinets that asked for nothing but one button pressed at exactly the right moment. The modern icon of the breed is Stacker, released by LAI Games in 2004: a wall of lights where a sliding row must be stopped directly above the row beneath, with any overhang wiped out. Reach the minor-prize line and you won candy or a keychain; land the single top row and the machine paid out an iPod or a game console, which is why Stacker towers drank quarters in malls all over the world.
The formula jumped to phones almost immediately. Digital Chocolate's Tower Bloxx in 2005 hung the block from a swinging crane and turned each drop into city-building, and Ketchapp's minimalist Stack in 2016 sliced pastel slabs on millions of commutes. Different skins, same heartbeat: a moving block, one input, and the sickening sight of your tower getting thinner.
Our Stacker strips the idea back to its arcade bones and drops it into your browser. There is no prize counter deciding whether you deserve the top row - Just the slide, your timing, and your own tallest tower. The machine finally plays fair; the only thing left to beat is your own hands.
Ways people play Stacker
- Prize-machine rules
- The 2004 Stacker cabinet format: stack to the minor-prize line for a small win, then risk it all on the climb to the major-prize row at the very top.
- Crane building
- The Tower Bloxx style - The block swings from a cable instead of sliding flat, adding a pendulum's momentum to every release.
- 3D slab stacking
- The mobile-era spin popularized by Stack in 2016: overlapping slabs in smooth 3D, where perfect drops slowly regrow your width.
- Target height
- Race to a fixed floor count instead of building endlessly. Reaching the line with the widest tower - Not just reaching it - Is the real score.
Stacker questions and answers
How does scoring work in Stacker?
Every block you land adds points, and perfect drops add a bonus on top. Consecutive perfects are worth more and more, so clean streaks are where big scores actually come from.
What counts as a perfect drop?
Landing the block flush with the one below, edges aligned. Nothing gets sliced, your tower keeps its full width, and the bonus registers instantly - You will hear and see the difference.
What happens to the part that hangs over?
It is cut off and falls away for good. Only the overlapping portion survives as the tower's new top, which is why every sloppy drop makes the next one harder.
When does a run end?
When there is nothing left to land - Repeated slices shrink the block until a final miss leaves no overlap at all. There is no timer; only lost width ends a run.
Why do the blocks slide faster as I climb?
Speed is the difficulty curve. Each floor nudges the slide quicker, so height is earned twice: once by your timing, and again by your nerve as the rhythm accelerates.
Is Stacker based on the arcade Stacker machine?
It shares the family tree. Prize cabinets like LAI Games' 2004 Stacker made stack-the-moving-row famous, but our version is pure skill - No prize odds, no house tricks, just timing.
Do the blocks always slide at the same speed?
Yes. Slide speed is tied to your height, so it climbs on the same schedule every game. That makes two of your own towers directly comparable: only your timing changed.
Can I play Stacker on my phone?
Perfectly. One tap anywhere on the screen drops the block, which makes this one of the best touchscreen games on the site. It runs in your mobile browser with nothing to install.
