Boltoria: Nut Workshop is a calm workshop puzzle with 5,000 fixed levels across five chapters. Learn classic sorting, hidden colors, locks, bolt capacities from 2 to 5, and combined master challenges. Every chapter is available immediately, while levels inside it are completed in order. A separate Program Mode lets you build a command queue and execute it strictly one move at a time. Undo, day and night themes, step-by-step tutorials, local progress, and leaderboards are included.
How to play
Select the source bolt, then the destination. Move nuts onto an empty bolt or the same top color; adjacent top nuts of one color move as a group when space allows. Watch bolt capacity, reveal ? nuts, and complete lock conditions. In Program Mode, build commands first and press Play to run them. Use ? to reopen the tutorial. Undo restores the previous move or command batch. Once per level, you may request an extra bolt through a rewarded ad.
