Knock the Blocks — The two roles and how the game works
About
OverviewKnock the Blocks is a two-player Roblox game where one player hurls objects at a Jenga-style tower while the other tries to stay on top and dodge everything coming their way. Roles swap after each round, so you need to be good at both sides. This guide walks you through controls, strategy, and how to get started.

The two roles and how the game works
Table
The game always needs exactly two players before it can start. One player takes the Destroyer role and the other stands on the Jenga tower. When a round ends, the roles switch automatically, so both players experience each side repeatedly.
| Destroyer | launches objects at the tower and the player standing on it, trying to knock them off |
| Tower | stands on top of the Jenga-style block tower and dodges everything thrown at them |
| Round end | roles swap automatically, so neither player stays in the same role forever |
| Starting requirement | the game will not begin until two players are present |
Playing as the Destroyer
StepAs the Destroyer, your mouse cursor controls where objects go. Point it at your target and click to launch. Your goal is either to hit the tower player directly or knock enough blocks out from under them that they fall. Because there are multiple objects available, you can keep firing from different positions.
- Aim your cursor move your mouse so the cursor points toward the tower player or the blocks beneath them
- Click to launch press the left mouse button to throw the object in that direction
- Switch objects different objects suit different angles, so try more than one
- Change your angle throwing from the same spot every time is easy to read, so vary where you aim
Playing on the Tower
TipsWhen you are the tower player, your job is to stay on top while blocks get knocked away beneath you. Use W, A, S, and D — or the arrow keys — to move around. The tower degrades as blocks are destroyed, so the safe ground keeps shrinking. Move early rather than waiting until something is already about to hit you.
- Use W, A, S, D or the arrow keys to move in any direction across the top of the tower
- React as soon as you see an object coming, not after it is already close
- Watch which parts of the tower have been broken away and avoid standing near those gaps
- Stay away from the edges — falling off ends the round just as surely as getting hit
Getting better at both roles
CheckEvery round hands you a new role, so weaknesses on either side will cost you. The Destroyer benefits most from unpredictability, while the Tower player needs sharp reactions and awareness of the shrinking platform. Repeated play with the same partner is the fastest way to sharpen both skills.
- As Destroyer, avoid falling into a predictable throwing rhythm that your opponent can memorise
- As Tower, practice moving the moment an object appears rather than hesitating
When you cannot find a second player
WarnThere is no automatic matchmaking that fills the second slot for you. If you join alone, you will simply wait. The most reliable fix is to invite a Roblox friend and have them join the same server at the same time.

Common questions
FAQCan I play this alone?
No — the game requires two players before it will start. There is no solo mode or bot to fill the second slot. Bring a friend and join the same server together.
How do I throw objects as the Destroyer?
Move your mouse cursor so it points toward your target, then press the left mouse button to launch the object. If clicking does not work, make sure the game window is selected and in focus on your screen.
What happens when I fall off the tower?
The round ends immediately. After that, roles switch automatically, so the player who just fell becomes the Destroyer in the next round.
