YOUR FIRST MATCH

A good tower has
a way up.

Stack or Sink is a survival game on Roblox. Build with everyday objects while danger rises below. Use a prop to gain height or attack a rival—but your own escape still needs a next step.

Start in Training Grounds

Follow the in-game prompts to learn the controls on your device. The context action changes with what you are doing: grabbing, stacking, throwing, or catching. Hold and release when the power meter appears.

Your first five moves

Find a useful prop. Start with an easy foundation rather than the tallest possible piece.
Place it where you can climb. Build reachable steps. A tower does not help if your next foothold is out of reach.
Keep moving upward. Watch the hazard and leave enough time to reach safety.
Choose your attacks. A prop thrown at a rival is a prop you cannot use for your next step. Check your escape first.
Respond to incoming throws. Eligible weak attacks can be caught or countered. Do not assume every object is safe to catch.

Survival wins

The tallest tower is not automatically the winning tower. Height rankings and the last survivor can differ. If eliminated, the Drop Deck offers controlled spectator participation before the next round.

Choose a way to practice

Use Solo Survival to focus on building. Public matches can fill empty seats with clearly labeled bots. Look for the in-game invite option when available to bring friends along.

Playing on a phone

Use the on-screen controls and follow the current action label. Keep both your next foothold and the hazard in view. Practice the hold-and-release timing in Training Grounds before battling rivals.
