The tower stack game for TikTok Live
The tower stack game from your feed — a streamer dropping one block at a time while the audience tears the tower down — is what Timmy's Tower is: a one-tap stacker built for TikTok Live where gifts chip (−1), hammer (−25), rocket (−75) and meteor (−150) the tower, heals rebuild it, and a nuke levels the whole thing in a cinematic finish. Every amount is validated on ScrollPlay's servers, and it runs on Windows in the free ScrollPlay launcher.

One tap, one block, one very hostile audience
A block swings across the screen; you drop it. Land it perfectly and the platform grows back wider — miss, and the overhang shears off and the tower gets thinner with every sloppy drop. That's the whole control scheme, which is exactly why it works on a live stream: viewers understand the game in one second, and every drop is a small verdict the chat reacts to.
Meanwhile the audience is armed. Attack gifts chip a block off for −1, hammer for −25, rocket for −75 and meteor for −150; a support gift rebuilds what you lost; and the finisher nukes the tower flat and ends the run outright. You're not just stacking against gravity — you're stacking against everyone watching.
Sprint or marathon — you set the stakes
Streamers set the goal and checkpoint with one-tap presets — 1K for a sprint, 100K for a session, 1M for a marathon climb that can carry a whole week of streams. The height, the goal and every gift amount are owned and validated server-side with a session nonce on every action, so the number on stream is always the number you actually earned; a tampered client can't fake its way to the goal your chat is paying to attack and defend.
Studio Mode puts the tower height and goal progress on stream as chroma-ready overlays, and the launcher's Actions page lets you rebind any TikTok gift to any effect — or author custom actions with your own amounts.
The duel version: two towers, two teams
When one tower isn't enough drama, Timmy's Tower Duel splits the screen in two: red tower versus blue tower, and the audience picks a side. Gifts build for your team or smash the other side's progress — and with the Save Timer overlay enabled in Studio Mode, a 1000-coin nuke on a tower puts a live countdown on stream for the audience to buy the rescue and bring it back. It's the same stacking core, turned into a team sport your chat plays against itself.
Not Ketchapp's Stack, and not "Stack High"
Two name-collisions worth clearing up. The minimalist mobile game "Stack" is Ketchapp's own title — a solo game, no relation to ScrollPlay. And the "Stack High" people search for is a mini-game played solo inside TikTok, not something a live audience can attack. Timmy's Tower is the third thing: an original stacking game built specifically so a live audience can fight over the tower with real, server-priced effects.

Frequently asked questions
What is the tower stack game everyone plays on TikTok Live?
A one-tap stacking game where the streamer rebuilds a tower while viewer gifts tear it down. Timmy's Tower is ScrollPlay's version: chip, hammer, rocket and meteor attacks, a rebuild heal, a run-ending nuke, and server-verified scoring.
How do I set up a stacking game on my own TikTok Live?
Download the free ScrollPlay launcher for Windows, install Timmy's Tower, connect your TikTok @username, then capture the game window in TikTok LIVE Studio or OBS. Set a goal preset (1K, 100K or 1M) and go live — gifts hit the tower in real time.
What do viewer gifts do to the tower?
Default bindings: a Rose chips −1, Gold Boxing Gloves hammer −25, a Doughnut rockets −75, Confetti drops a meteor for −150, and a Galaxy nukes the tower flat, ending the run. A Rosa rebuilds the tower. Every amount is enforced server-side, and you can rebind any gift.
Can viewers knock my tower down completely?
Yes — the nuke levels it in a cinematic finish that ends the run. In the Duel version there's a twist: with the Save Timer overlay enabled in Studio Mode, the audience can buy the rescue on a countdown after a nuke and restore the tower to its pre-nuke height.
Is this the same as Stack High on TikTok?
No — that's a mini-game people play themselves inside TikTok. Timmy's Tower is a desktop game for live broadcasts where the audience participates through gifts, likes and follows.
Is Timmy's Tower related to Ketchapp's Stack?
No. Stack is Ketchapp's trademark and ScrollPlay has no affiliation with them. Timmy's Tower is an original one-tap stacker in the genre, built for TikTok Live streaming.
Do viewers need to download anything to attack the tower?
No. Viewers just watch your LIVE and send ordinary TikTok gifts — the launcher turns them into chips, hammers, rockets, meteors, heals and nukes.
Stack is a trademark of Ketchapp. ScrollPlay and Timmy's Tower are not affiliated with, sponsored by, or endorsed by Ketchapp — Timmy's Tower is an original ScrollPlay game inspired by the genre the classic made famous.
