StackBreak 2D — Game guide

Nothing to install: it opens on Roblox, and the gifts from your live stream do the rest.

StackBreak 2D is TntCube 2D's wrecking-crew twin: the side-on stack is already full when you walk in, and your job is to bring it down while the gifts from your TikTok live either help you demolish it or put it back up. It runs on Roblox, so there is nothing to download and no server to set up: all you need is a Roblox account linked in your profile on the site.

How a run works

The field is an obsidian yard with no walls and no cage: just the floor, with the stack sitting on it. The stack is 30 columns wide and 18 rows tall, split into three bands of six — iron at the bottom, gold in the middle, diamond on top. Your character spawns on the ground next to the yard, on the right, with the stack to their left.

You break the block in front of your character: the adjacent column in the direction you are facing, at foot level. Whatever sits above drops down a step, because the stack has its own gravity and never leaves blocks hanging — even the bites opened by TNT compact downwards. Breaking from the base, iron goes first, then gold, then diamond: the bands tell you at a glance how far along the run is.

There are two ways to demolish, and you pick from the in-game menu: Manual (right click, click or hold for a burst; on phone the ⛏ button) or Auto, one collapse every half second while you stand still on the stack, with the rate adjustable from 0.05 to 2 seconds.

When the stack is levelled to the floor a countdown from ten starts, amber down to 4 and then red and slower for the last three. If it hits zero that is +1 win: the celebration plays, the stack fills back up and you start again. If someone puts blocks back with a gift in the meantime, the countdown is cancelled and you have to finish the job.

What the gifts do

These are the actions you can link to TikTok gifts from the dashboard. The codes are the same as TntCube 2D, but here the roles are flipped: since the game is to demolish, whoever helps you is whoever breaks — TNT, fireworks, collapses — and whoever works against you is whoever rebuilds the stack. If you come from TntCube 2D and reuse the same setup, your "good" and "bad" gifts swap places.

Action	What it does	The amount
`tnt_drop`	On the side of whoever helps you. Rains TNT onto the stack: the bite it opens collapses downwards.	How many TNT
`firework`	On the side of whoever helps you. Like the TNT but with a wider radius, and with confetti.	How many fireworks
`block_remove`	On the side of whoever helps you. Knocks bases out of the tallest columns: whatever sits above drops.	How many bases
`clear_all`	On the side of whoever helps you. Levels the stack in one go, win countdown included.	Ignored
`block_add`	On the side of whoever works against you. The stack grows back from the bottom, on the emptiest columns.	How many blocks
`fill_all`	On the side of whoever works against you. Stack full again, all the work to do over.	Ignored
`win_add`	Adds wins to the counter, without touching the stack.	How many wins
`win_remove`	Takes wins off the counter.	How many wins

A big block_add or fill_all grows the stack back under your feet too: it does not hurt, but you end up lifted with half the run to do again.

Linking gifts to actions

The "this gift does this thing" rules are written in the dashboard, in the Events & Actions tab, inside a profile dedicated to this game. Each slot holds a gift, an action and its amount, and has a switch to turn it off without losing the setup.

Before you go live, remember two things: the TikTok @ linked in your profile has to be the one you stream from, and the session has to be started from the dashboard — without it the game just sits there and gifts make nothing happen.

Inside the game, the 🎁 section of the menu shows the gift legend: the on-screen list of what does what, which your audience sees while you play.

Section	What you find there
🏆 Win	The win counter and the target.
🔊 Volume	The game volumes, separately.
🌅 Sky	The backdrop of the scene.
🎮 Game	Manual or Auto demolition, the auto rate (from 0.05 to 2 seconds), the arena style and the reset button.
🎁 Gifts	The on-screen legend of what every gift does.
🧪 Test	Try the actions without waiting for a real gift: it is how you tune the amounts before going live.
🌐 Language	The language of the on-screen text.

The floor style can be obsidian, glass, black or netherrack, and stays saved on your account for the next runs. The skies are the same as the other TikForge Roblox games: a random one is set on every launch, and your saved choice overrides it as soon as you walk in. The camera is front-on and follows the character: zoom with the wheel or pinch on phone. You walk slowly and run by holding Shift.

Things worth knowing

TNT does not hurt you: it only eats blocks. There is no way to die, the run never stops.
There are no walls: the world is just the floor, and the barriers that keep you inside the area are invisible. The scene stays clean for the stream.
No blocks left hanging: anything that takes a block out from underneath — you, a collapse or a TNT — drops everything above it down a step. Blocks keep their colour as they fall.
The bands are the score: as long as you see diamond you are at the start, when only iron is left you are nearly done.
Codes from other games are ignored: the trigger queue is shared across TikForge's Roblox games, and this game only runs the actions listed above. A profile written for another game breaks nothing, it simply does nothing.

The win counter stays saved on your Roblox account: what you win is not wiped when you close the game, and you find it again on your way back in, along with the target you set yourself.
