Ever thought about turning the art of coffee roasting into a strategic challenge? In Coffee Roaster, you step into the shoes of a master roaster in a purely solitaire experience where the goal is sensory perfection. The gameplay revolves around bag building: you select the coffee bean varieties you wish to process and place specific tokens into a bag. Each turn, you randomly draw tokens to advance the roast level of the beans. But beware: simply hitting the target level isn't enough. The secret lies in consistency. You must ensure that all beans of a particular variety reach the same roast level, avoiding a mix of under-roasted and over-roasted beans.

The game demands precise management of your bag's contents. You'll have to deal with nuisance tokens, such as smoke and burnt beans, which hinder your progress and can ruin the final flavor. To succeed, you'll need to leverage flavor effects and special abilities triggered by placing tokens on the roast board. With 22 different bean varieties available, each game focuses on roasting three of them, ensuring high replayability. At the end, you perform the 'cup-testing' — the final taste test — to calculate your score. If you are precise and strategic enough, you can earn the ultimate title of 'Meister'. It's a game of risk management and memory, perfect for those who love tactical puzzles and want to relax (or get a bit stressed) while trying to brew the perfect cup of coffee.
