Bubble Gum Simulator

Bubble Gum Simulator is an incremental pet simulator on Roblox by Rumble Studios, launched in October 2018 and now carrying over 1.24 billion visits and 3.3 million favorites. Built around a vertical progression system where players blow bubble gum to jump higher through floating cloud worlds, it helped define the pet simulator genre formula on Roblox - countless successors borrowed the "blow gum to reach better worlds, hatch better eggs" loop that BGS pioneered.

The core loop is vertical: click to inflate your bubble until full size, float upward, bounce on clouds to reach higher floating islands, collect currency by landing on platforms, sell for Coins, and spend Coins on upgrades and Eggs. Hatching eggs produces Pets that boost your stats. Better pets mean bigger bubbles and higher jumps, which unlock access to even better eggs in worlds further up. The cycle compounds continuously, giving players the following progression layers:

• 🗺️ Themed Worlds - Floating Island, Outer Space, Twilight, Void, and Zen, each containing multiple islands accessed by jumping high enough
• 💎 Pet Rarity - ranges from Common through Legendary to Mythic, with Shiny variants offering 1.5x-3x bonus multipliers on top of base stats
• 🏆 Luck - increases the probability of rare and Legendary pets from eggs; the primary stat to stack before hatching sessions
• ⏳ Hatch Speed - reduces time between egg hatches, allowing more rolls per hour; pairs with Luck for efficient rare pet hunting
• 💼 Code Stacking - running simultaneous Luck and Hatch Speed boosts before a focused session is the recognized meta strategy for chasing Mythic pets
• 🎭 Trading - player-to-player pet trading unlocks after 2,000 total egg hatches; Mythic and Shiny pets carry the highest trade values

Two stats drive everything: Luck and Hatch Speed. Both are also the two most common code reward types in the form of timed 2x multipliers. A notable quirk: BGS codes are NOT case-sensitive, which is unusual for Roblox games and means typos from capitalization errors never break a redemption attempt.

Rumble Studios launched Bubble Gum Simulator INFINITY in April 2025 as the active successor with expanded mechanics and weekly updates. The original BGS is now in maintenance mode but retains its massive code library - 200 active codes, one of the highest counts of any Roblox game - making it worth playing alongside Bubble Gum Simulator INFINITY.
