PC Controls
Full keyboard and mouse controls for Merge a Black Hole on Roblox PC — merge shortcuts, raid aiming, camera movement, and base lock.
Playing Merge a Black Hole on PC offers the most precise control over merging, raiding, and base management in this popular Roblox merge-raid-idle sim from XAF Games. With over 3 million visits and a thriving raid meta, desktop players often lead the pack in competitive base assaults thanks to mouse accuracy and quick keyboard camera adjustments.
This guide documents every PC input you need, from first merge to late-game rebirth resets. If you also play on phone or console, compare notes with the main Controls Guide and the mobile and console controls page.
Getting Started on Desktop
Launch Merge a Black Hole through the official Roblox game page or your Roblox home screen. Once your base loads, you spawn on the merge board with starter black holes generating passive cash. PC players use WASD or arrow keys for character movement when walking around the base, and the mouse for nearly all merge and menu interactions.
Roblox default camera controls apply: right-click and drag to rotate view, scroll wheel to zoom. Some players enable Shift Lock in Roblox settings for a fixed over-the-shoulder angle that makes raid aiming more predictable.
Merge Board — Mouse Controls
Merging is the idle backbone of Merge a Black Hole. On PC:
- Left-click and hold on a black hole to pick it up.
- Drag it over another hole of the same tier.
- Release left-click to merge into a higher tier.
Higher tiers increase cash per second, fueling faster progression and stronger raid payloads. Drag speed matters during timed events — practice quick merges before Admin Abuse + Rebirths weekends when bonus multipliers stack.
If your merge board fills, sell or reposition low-tier holes using the trash or storage icons (exact label varies by update). Check the Tier List so you never waste slots on holes that fall off the current meta.
Raid Controls — Keyboard and Mouse
Raiding separates casual merge players from top earners. From your base HUD, open the Raid menu with a left-click on the raid button or map icon. Select a target base, then enter raid mode.
| Action | Default PC Input |
|---|---|
| Aim black hole | Move mouse |
| Charge launch | Hold left-click |
| Quick launch | Tap left-click |
| Cancel / back | Escape or UI back arrow |
| Camera rotate | Right-click drag |
| Zoom | Scroll wheel |
Charged shots deal more structural damage but take longer. Speed raiders prefer quick clicks to flood defenses before opponents lock. Experiment in low-stakes targets before attacking stacked bases.
After a raid, click Collect on the reward popup. Return home via the UI teleport button. Immediately lock your base — see below — before queueing another raid.
Base Management and Lock
Your vault stores uncollected earnings. Click Collect on cash piles regularly so raiders steal less. The Lock Base button is usually near the vault or shield HUD element. Left-click once to enable; the icon glows or changes state when active.
Unlocking happens automatically when you initiate a raid or manually toggle lock off. Develop the habit: raid → collect → lock → log off. New players learning the loop should read the Getting Started Guide for economy tips alongside these inputs.
Codes, Shop, and Menus
Redeem Game Codes via the Codes icon upper-right. Click the icon, type or paste a code, press Redeem. Codes grant cash and stars that skip early grind — verify working codes on our codes page before each session.
Roblox Esc opens the platform menu (not in-game shop). In-game shops use clickable UI panels. Rebirth menus, added in major updates, appear as dedicated buttons after progression milestones — use the Rebirth Calculator to time resets optimally.
Advanced PC Tips
Graphics settings: Lower Roblox quality if merge drags feel sluggish during large boards. Smooth FPS helps precise raid aim.
Dual monitor: Keep this wiki or the Weekly Updates page open on a second screen during Sunday patches.
Keyboard focus: Click the game window before merging; lost focus sends inputs to the browser instead.
Server choice: Less crowded servers reduce raid queue lag on PC broadband connections.
Sunday Updates and PC UI Changes
XAF Games ships weekly Sunday updates. PC HUD layouts occasionally shift when rebirth systems, admin events, or new hole tiers arrive. After each patch, skim the Updates hub and test merge and raid inputs in a private base before competitive raiding.
