Coaster and Plunge

Coaster and Plunge is a roller coaster incremental simulator on Roblox developed by Black AA Studio where players ride their personal coaster down a mountain, collect coins along the track, and reinvest earnings into equipment and pets to improve each subsequent run. Launched in November 2025, it reached 12.4 million visits within its first few months and holds a 97% approval rating - one of the strongest satisfaction scores for a new simulator on the platform.

Each run begins at the mountain peak and ends at the plunge - the fast downhill section where coins are most densely packed and speed peaks. Between runs, collected Coins fund two categories of upgrades that make each subsequent run more rewarding:

• 🚗 Equipment - upgrades to coaster stats including speed, coin collection range, and plunge bonuses
• 💎 Pets - companions that multiply coin earnings passively on every ride without active input
• ⏳ Stamina - the resource governing run frequency; refills over time or restored instantly via potions
• 🏆 Trophies - a score metric tracked on the server leaderboard among up to 15 players per server
• 💰 Coin Potions - temporary multipliers on coin earnings, most useful when grinding toward the next equipment tier

The pet system is more involved than typical incremental simulators. Pets have rarity tiers, hatch from eggs using gems earned in gameplay, and lucky modifiers affect hatch probability across three tiers - lucky, Super Lucky, and Ultra Lucky. Multiple equip slots mean building a pet lineup rather than relying on a single companion.

Coaster and Plunge sits in a fast-growing lane within the Roblox simulator space, combining the satisfying physical loop of a coaster run with a structured upgrade progression. For a similar incremental experience with a different theme, see Mining Simulator 2.
