S S Tier — Best Income
A A Tier — Strong Income
B B Tier — Solid Mid-Game
C C Tier — Early Game
D D Tier — Decoration Only
Upgrade Priority
Early game: buy Small Blocks and Walls to build income. Mid game: save for Ice and Rainbow Truss. Late game: max tower upgrades before cosmetic blocks.

Upgrade Strategy
- Upgrade to level 3–5 early to unlock enough item slots for income scaling.
- Do not rush to max level — balance upgrades with buying high-income blocks.
- Each upgrade increases offline earnings potential by expanding your tower capacity.
- Late-game upgrades (10+) require billions — plan your income before committing.
# Gear
Four gear types are available from the shop (restocks every 5 minutes). Each has limited uses — spend them strategically.
Hammer
Default tool for placing, rotating, and adjusting blocks. Equip from inventory before building.
Teleporter
Instantly teleports you to the highest block in your tower. Essential for testing long obby routes.
Refiner
Reposition blocks after placement. Save for fixing mistakes on expensive layouts.
Paint Bucket
Customize block colors. Purely cosmetic — buy only after income is stable.
# Controls
Mastering placement controls is key to building functional obby courses and maximizing your tower layout.
PC Controls
| Move | W / A / S / D |
| Jump | Space |
| Place / Use Item | Left Click |
| Rotate Block | R |
| Adjust Height | E / Q |
| Camera Angle | Mouse |
| Equip Hammer | Inventory Slot |
Mobile Controls
| Move | Virtual Joystick |
| Jump | Jump Button |
| Place / Use Item | Tap Screen |
| Rotate Block | Rotate Button |
| Camera | Swipe / Drag |
| Equip Tools | Inventory Bar |
Your character moves slower while holding objects. Use camera angle adjustments to place blocks precisely before confirming placement.

Advanced strategies to maximize income, design better obby courses, and progress faster.
Income Optimization
Fill every item slot with the highest $/s blocks available. Replace low-tier decorations with income generators as you progress.

Offline Earnings
Your tower generates Cash while offline. Maximize placed blocks before logging out for the best passive income.
Obby Design
Balance difficulty with flow — test your course with Teleporter. Precise block placement prevents glitches that frustrate visitors.
Friend Permissions
Control who can build on your tower. Allow trusted friends to collaborate on obby design while protecting your layout.
Sell Smart
Sell low-income blocks back to the shop when you need Cash for upgrades or rare items. Do not sell high-tier blocks unless replacing them.
