Boxing Simulator!

Boxing Simulator is a Roblox incremental simulator by Tetra Games where players punch training bags to build Strength, sell Strength for Coins, evolve characters using Souls, hatch pets with DNA, and compete in PvP duels. The current version is tagged [X100], meaning Strength gain is multiplied 100x for dramatically faster early progression. The game has over 124 million visits and a 93% approval rating from over 393,000 votes since its October 2019 launch. The most recent update was December 2025.

The progression system is unusually deep with four currencies running in parallel tracks:

• 💪 Strength training - punching bags builds the core Strength stat; selling Strength earns Coins for weapons and DNA upgrades
• 🗺️ Island zones - each island requires a Strength threshold to unlock and offers stronger training spots, tougher dungeon enemies, and higher rewards
• 💎 Pet gacha - Gems fund egg purchases to hatch pets with passive Strength multipliers; higher-rarity pets give larger bonuses
• ⚔️ PvP duels - players challenge each other to boxing matches for currency rewards and global ranking standings
• ⏳ Evolution system - Souls (earned at high levels) are spent at progression milestones to evolve your character
• 💰 Dungeon mode - fight monsters in dungeon areas for additional currency rewards outside of standard training

Joining the Tetra Games Roblox group gives a 20% Coins bonus and a chat tag as a persistent free perk. The code history includes one of the largest single-code rewards documented anywhere on Roblox: the INFINITY code giving 10,000,000 Gems. Additional notable codes include KSIWON (giving Strength, referencing the KSI vs Logan Paul fight at the game's October 2019 launch) and YouTube creator codes SUB2GAMINGDAN and SUB2COOKIE. With 18 active codes tracked, Boxing Simulator is one of the more code-generous games in the simulator genre.
