Merge Factory

Buy small machines, drag two of the same level together to build a better one, and watch a factory floor full of coin machines pay out.

How to play

Buy a level 1 machine to place it in the first free slot on the 4 by 4 factory floor. Each machine earns coins every second.
Tap a machine, then tap another of the same level to merge them into one machine a level higher. Tap an empty slot to move a machine instead.
Higher level machines earn much more than two lower ones, so merging is the main way to grow.
Spend coins on a factory boost to double all income. There are six boosts and each costs five times the last.

Keep a free slot or two so you can always buy and merge. A full floor stops you buying.
Merge as soon as you can. The new machine pays more than the two it replaced.
Buy a boost once you have a few good machines. It multiplies everything at once.
Machines keep earning at half speed for up to an hour while the page is closed.

Can I drag machines?: Tap one machine, then tap the target slot. That works the same on a phone and with a mouse.
What is the highest machine level?: Level 12. Machines at that level cannot be merged further.
Is my factory saved?: Yes, automatically, in this browser only.
