Merge Simulator

Merge Simulator is the definitive merge game on Roblox by Pixel Bunny Studios with 136.6 million visits - by far the highest-visited title in the merge genre. Players combine color-coded blocks on a grid to generate Cash, hire Minions to automate the merging, rebirth for Gems, and reinvest Gems into OP upgrade tiers that scale progression exponentially. The game's mechanical clarity - merge always upward, reinvest always - has driven its position as the genre reference point since launching in September 2022.

The loop is clean and self-reinforcing:

• 💰 Merge two identical blocks to create the next tier, which generates more Cash per second than either block it replaced
• 🏠 Hire Minions to merge blocks automatically, converting the active clicking loop into idle income
• 🏆 Track your progress through Slime block tier badges - Block 1 through Block 6 form the Slime phase, with higher categories following
• 💎 Rebirth your board for Gems, then spend Gems on OP upgrades that multiply future efficiency well beyond what Cash can buy
• 💰 Buy Cash upgrades to speed up merging and increase block value across all current tiers simultaneously

Block progression is tracked by five milestone badges: Block 1 (33.7M awarded, essentially all players), Block 6 (25.2M, 69.6%), Block 12 (17.9M, 55.1%), Block 18, and a high-tier block - each representing a meaningful stage of the grinding journey. The Infinite Rebirths gamepass (699 R$) removes the rebirth cap, and the Auto Clicker (550 R$) clicks all blocks every second for fully automatic progression. Monetization relies entirely on gamepasses targeting the two main friction points: rebirth limits and manual clicking. If you enjoy the loop here, Merge Titan Army and Merge Drills run similar mechanics.
