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 when a 1000-coin nuke flattens a tower, the game puts a rescue countdown on stream for the audience to buy 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?
Open Web Launcher on Windows, Mac, iPhone/iPad or Android, or use the Windows desktop launcher. Sign in, choose a game and connect your TikTok LIVE in Studio. Capture your browser/game window on a computer, or share your phone screen using the streaming options available to your TikTok account.
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: after a nuke the game runs a rescue countdown, and if a viewer sends that side's Save Tower gift in time, the tower comes back 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 an interactive 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.
