Swap places of block in such a way to have at least three of the same kind next to one another (horizontally or vertically). You are only allowed to swap blocks that are next to each other.

You are Sergey and you are hardly working for an extremely low eCPM in the Tetra Block Factory, Production Department, 3rd night shift. Your job is to continuously detect and fix defective tetra-blocks which will be delivered...

Run a new factory every day making new items in each one. Put the items together then ship them, make sure you don’t break anything or else you’ll lose money! Can you be the highest earner?

Creeps move on multiple paths, and have 4 different spawn portals! So, you must be able to build your towers strategically to defend your factories. Also, the game is automatically saved every wave.
