Roller Coaster Looper

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.

Earn While It Loops

While your coaster runs, a lightweight idle layer runs with it. Tap decorations to generate bonus thrill and XP. Level up during the ride to earn Win Points, then spend them on run-scoped upgrades: crank up simulation speed, boost base thrill per segment, or juice your click power even further. Veterans start each run with more Win Points based on how many unique win combinations they've racked up. It's entirely opt-in: ignore it and you'll still finish the run. Lean into it and the numbers get very silly very fast.

Keep Building Between Runs

A Research Lab of challenges tracks your lifetime accomplishments and unlocks permanent upgrades. New rider types, new segment variants, new decorations to add, new card archetypes. Each run means your next run will have even more options.
