Roller Coaster Looper is a roguelite idle-like coaster-builder where strategy happens in the shop and satisfaction happens on the track.
Between rounds, you browse a rotating market of track segments, eccentric riders, and decorations. Then watch your choices play out as your coaster loops endlessly, stacking thrill multipliers and generating increasingly unhinged reactions from your passengers.

Build the Loop
Draft from 24 unique track segments each with distinct thrill values and special effects. Slow Burn ignites with every loop. The Slingshot launches into the next segment for bonus multipliers. The Haunted Stretch slowly fades away over time. Every purchase shapes the run.
Recruit the Riders
Fill your train with any of the 29 waiting riders, each with their own personality, synergies, and scoring quirks. The Gambler has a 20% chance to triple their score (or nothing). The Dare Devil loves inversions. The Conductor is a robot rider that is more thrilled the longer the train gets. Matching the right riders to the right track is how the big numbers happen.
Stack the Cards
Discover and activate card modifiers that bend the rules across an entire run. Boost specific rider types, unlock combo chains, multiply thrill in exponential ways. Card packs game changing but expensive, crack them open and adapt your strategy on the fly.
Survive 12 Rounds
Each run is 12 rounds of escalating goals. Meet the thrill target, keep your riders happy, and don't lose all your stars. Every third round, a boss modifier changes the rules: bigger requirements, new constraints, and a reward for winning. Make it to the end of Round 12 and you've built something special.
