+ Blocks Every Second

+1 Blocks Every Second is a tower-building incremental simulator on Roblox developed by Under The Bed! where players passively accumulate one block per second, click to build their tower faster, and use Rebirths to trade current progress for permanent speed bonuses. The stated goal is to build your tower all the way to space. Launched in January 2023, it is one of the earlier entries in the "+1 every second" Roblox genre, accumulating 125 million visits and a 94% approval rate from over 120,000 votes - an exceptional rating for a simulator running for more than three years.

The core loop combines three reinforcing mechanics: passive block generation at one per second, active clicking that places blocks faster scaled by your Pet companions, and a Rebirth prestige system that resets your block count in exchange for a permanent +1 Blocks Per Second bonus per reset. Each Rebirth makes the next cycle faster, and the tower itself is the visible measure of how far you have come. A badge progression system tracks 18 distinct tower material tiers from basic to rare, giving players clear targets at every stage:

• 🏠 Tower materials - 18 progression tiers from Wood Tower through Copper, Emerald, Diamond, Obsidian, and Gold, each a named badge milestone
• 💎 Pets - companions that multiply blocks earned per active click, hatched from eggs and improved through the pet system
• 🏆 Rebirths - prestige resets that permanently add +1 Blocks Per Second to your passive rate, stackable across unlimited resets
• 💼 Auto build - the Fast Auto and Double Build Speed passes automate and accelerate the construction process for idle play
• 💰 Pet passes - Ultra Lucky, Auto Open Eggs, Fast Hatch, and Triple Eggs target the pet drop system for players focused on maximizing click output

Pets are the primary active-gameplay system. Higher pet quality means more blocks per click, and multiple pet slots from the +5 Pet Equip Slots pass allow stacking bonuses. Roblox Premium adds +2 Walk Speed. The Double Blocks pass permanently doubles all block production - the most impactful single pass for tower speed.

+1 Blocks Every Second is one of the genre's foundational titles and shares its idle tower-building loop with +1 Block Every Second, which adds world zones and a pet fusion system as a natural next step for players who enjoy this format.
