+1 Block Every Second

+1 Block Every Second is an incremental tower-building simulator on Roblox where players passively earn one block per second and stack them into an ever-taller tower - eventually reaching space and the Oblivion Planet beyond. Developed by 48h Studios and launched in January 2023, it is one of the original entries in the "+1 per second" simulator genre, accumulating 18.3 million visits and a remarkable 945K favorites - a 5.1% favorites-to-visits ratio that reflects how deeply its idle loop resonates with its audience.

Three interlocking systems drive progression: passive Block accumulation at one per second, active clicking scaled by equipped Pets, and a Rebirth prestige cycle that resets your block count in exchange for a permanent +1 Blocks Per Second bonus. Tower height is both the primary progression metric and the mechanism that raises your pets' level cap, meaning building floors is never wasted effort. The world structure expands upward through earth, sky, space, and beyond, with each zone introducing new themed eggs and exclusive pets:

• 💎 Pet Mix - fusion system that upgrades duplicate pets from Normal through Gold, Shiny, and Rainbow tiers, each providing a stronger click multiplier
• 🏠 Pet Index Machine - lobby structure added in the Oblivion update cataloging every obtainable pet for collection tracking
• 💼 Potion Shop - sells instant upgrade potions for max level, Gold, Shiny, and Rainbow tier pets, letting players bypass the fusion grind entirely
• 🗺️ Oblivion Planet - the current furthest world, adding two new eggs, 20 new pets, and a hidden-object discovery mechanic above the sky
• 🏆 Rebirth milestones - badge-tracked from the first rebirth through the 50th, with each cycle permanently raising passive blocks per second

Pets are the deepest system in the game. Hatching eggs produces Normal pets; combining duplicates through Pet Mix upgrades them to Gold, then Shiny, then Rainbow - the rarest and most powerful tier. Your tower's floor count sets the pet level cap, so tower height directly feeds into pet strength. Roblox Premium adds one extra equip slot, a genuine advantage when stronger pets mean larger per-click multipliers. New codes and updates release at like milestones, with the current target posted in the game description.

48h Studios announces codes first through their Discord server's dedicated codes channel, then on @48hStudios on Twitter/X. Code names mirror the content they launch with ("oblivion," "heaven," "alien"), so following the Discord around major update windows is the most reliable way to catch codes before they expire.
