Crab Tycoon Controls

Crab Tycoon by Atlantean Co. plays like a standard Roblox idle merge tycoon: most actions use simple clicks or taps rather than complex combos. Understanding where each menu lives and how drag-merge works on your device prevents early frustration — especially when redeeming codes, buying crabs, or clearing shell piles before capacity caps. This reference covers PC, mobile, and the in-game UI in one place.

PC Mouse and Keyboard Controls

Desktop Roblox players interact primarily with the left mouse button. Click crabs to pick them up, move the cursor to a matching tier mate, and release to merge. Click empty beach tiles to place purchased crabs from the shop. Right-click or scroll wheel drag typically rotates and zooms the camera depending on your Roblox camera mode — adjust in Roblox settings if sensitivity feels wrong.

• Left click: Select, drag, merge, and confirm UI buttons.
• Camera drag: Hold right mouse button or use Roblox default camera keys to pan the beach.
• Scroll wheel: Zoom in on dense crab clusters during late-game base management.
• Keyboard: No dedicated hotkeys for shop or merges — all economy actions are mouse-driven.

Open the shop via its HUD button (usually along the bottom or side toolbar). Spend cash on new crabs, capacity expansions, and appraisal speed from there. The settings cogwheel in the top-right opens code redemption — walk through our redemption guide when claiming promos like SANDCASTLE.

Mobile Touch Controls

iOS and Android clients map the same actions to touch. Tap and hold a crab, drag to its twin, and release to merge. Single taps activate buttons, incubator timers, and offline claim prompts. Pinch-to-zoom helps navigate crowded bases once you reach mid-tier crabs from the tier list rankings.

Paste codes on mobile by long-pressing the Redeem Codes field inside settings. Disable autocorrect before typing manually — codes demand exact capitalization. Touch targets for the cogwheel and shop icons follow Roblox safe zones; rotate to landscape on tablets if buttons feel cramped.

In-Game UI Overview

The HUD splits between resource displays, action buttons, and contextual panels. Cash and shell totals appear near the top or side depending on layout patches — watch both because shells must be appraised into cash through the appraisal interaction or automatic conversion once speed upgrades kick in. Details on shell flow live on the items and resources page.

Core UI Elements

• Shop: Buy crabs, unlock tiers, expand capacity, upgrade appraisal speed.
• Settings (cogwheel): Redeem codes, adjust audio, access support links.
• Incubator: Place eggs for roughly twenty-four-hour hatches — see the hatching guide.
• Appraisal zone: Convert accumulated shells to cash; speed upgrades reduce wait time.
• Offline claim popup: Appears on login after time away — covered in offline earnings guide.

Merge and Placement Mechanics

Merging requires two identical crabs of the same tier. Drag one onto the other; the pair combines into the next tier variant listed on the crab tier table. Invalid drops bounce back without consuming crabs. Fill capacity with low tiers first, then chain merges upward — the core loop explained in how to merge crabs and the full walkthrough.

Empty slots accept new shop purchases. When full, you must merge or sell (if available) before buying more Tier 1 fillers. Smart players avoid clogging slots that block egg rewards or high-tier merges during mid-game spikes described in cash optimization guide.

Camera and Quality-of-Life Tips

Roblox graphics settings affect frame rate on low-end phones — lower quality keeps merge drags responsive during heavy shell particle effects. On PC, fullscreen mode reduces mis-clicks near window borders when rapidly merging during boost sessions. Join the community via our Discord guide when patches rearrange HUD buttons; veteran players share updated screenshots after major UI changes.

Controls stay consistent across sessions: no secret gestures unlock hidden menus. Master shop purchases, settings redemption, and drag-merge first — everything else in Crab Tycoon builds on those three interactions tied to upgrades in the upgrade guide.
