TNT Jump!

TNT Jump! is a physics-based incremental simulator on Roblox where players buy TNT blocks, detonate them to launch themselves skyward, earn Cash from the height of each blast, and reinvest in increasingly powerful explosives. Developed by holytail Studios and launched in April 2025, the game has surpassed 2.26 million visits with a 96.4% approval rating, showing strong retention for a niche physics-incremental.

The core loop is satisfying and escalating: buy a TNT block, detonate it, earn Cash proportional to how high you flew, spend that Cash on better TNT with more Blast Power, and repeat. Each tier of TNT launches you meaningfully higher than the last, and the jump from early-game sticks to later explosive types creates a genuine sense of escalating power:

• ⏳ Sky Islands - Altitude-tier unlock zones in the upper atmosphere, each gating new content and progression challenges
• 💰 Rebirth - Prestige reset that trades current progress for permanent Cash multipliers, compounding with every reset
• 💎 Potions - Consumable boosts that temporarily increase Cash gain or Blast Power, extendable via the Extended Potions gamepass
• 💰 Special TNT - Timed event TNT spawns with high payouts; the Pro Alerts gamepass notifies players and teleports them in

Storage caps how many TNT blocks and items you can hold at once. The default cap is low, and the Extra Storage gamepass raises it to 300 slots, which matters when stacking up for a big blast session. Cash is the only currency - everything from TNT upgrades to gamepass perks runs through the same economy.

TNT Jump! occupies a narrow but loyal corner of Roblox physics simulators. Its absurdist "blow yourself up for profit" loop sets it apart from distance-throwers like Throwing Simulator or idle farm incrementals that dominate the broader simulation genre.
