Catch Critters

Catch Critters is a rock-flipping critter simulator in BETA by Boink Studios on Roblox, launched July 2025. It has reached 3.14 million visits with a 90% approval rating, and features seven active codes tied to a milestone system where new codes unlock at like thresholds.

The game centers on a simple tactile mechanic: walk the world, flip rocks, and catch whatever is underneath. Each critter you find falls into one of four rarity tiers, and you can sell them for cash or equip them to boost future sell prices:

• 🗺️ Rock flipping - interact with rocks scattered across the map to reveal critters hiding underneath
• 💎 Four rarity tiers - Common, Uncommon, Rare, and Legendary critters each carry different sell values
• 💰 Sell or equip - selling gives immediate cash while equipping a critter adds a percentage bonus to all future sell prices
• ⚔️ Luck upgrades - the 2X LUCK gamepass (200 Robux) doubles the chance of finding rarer critters under rocks
• 🗺️ Rock Searcher pass - unlocks more rocks in the world for 150 Robux, increasing the rate of discoveries

Two currencies drive the loop: cash from selling critters funds upgrades and gear, while the Rock Searcher and 2X LUCK passes accelerate the pace. The developer posts new codes when the game hits like-count milestones, with the code MOON active and listed directly in the game description.

Boink Studios has released seven codes for Catch Critters, rewarding cash amounts from 5K up to 100K and special items like the Net Box [OP]. If you enjoy the critter collection loop, Catch Bugs! [JUNGLE] offers a similar catch-and-sell structure with active bug hunting instead of rock flipping.
