Marble Racing Manager

Marble Racing Manager is an idle simulator where you collect marbles and watch them compete in automated races. You start with free gems to buy your first marble, then expand your roster over time. Drop marbles into a racing tray and they'll enter competitions every 60 seconds without you lifting a finger. Races generate rewards automatically, and the system keeps running even when you close the game. Your marbles earn resources while you're away, so checking back after hours nets accumulated progress. The core loop is simple: spend currency on new marbles, assign them to race slots, collect what they've earned, and reinvest in more marbles or upgrades. It's built for players who want progression without constant attention—set it up, let it run, return when convenient.
