Marble Sort
Marble Sort asks you to arrange colored marbles that circulate continuously in order to fill the correct slots with three identical elements. First, you choose a bin to open to send new marbles onto the circuit. Then, you guide them to the corresponding supports taking into account their color and the space still available. Each support is validated only when it contains exactly a matching trio, otherwise it remains an area to manage for the rest of the level. The objective is therefore not only to move what passes in front of you, but to build an efficient order until all bins are emptied. If you distribute the colors poorly, the belt becomes harder to read and your next decisions lose effectiveness.
The logic of the game relies on anticipation and on flow management. You must think about what opening a bin will add to the circulation, then decide whether it is better to complete a set already started or prepare a safer future placement. Otherwise, you risk scattering identical colors across several supports and slowing your progress significantly. The difficulty comes from this balance between immediate action and preparation, because a correct short-term solution can create a blockage a few moments later. The game remains easy to understand, but it becomes subtler as several colors cross and choices interact. Each level thus renews the thought process, since the order of moving marbles and the state of the supports constantly change the best possible decision. Have fun!
