Number Merge Factory
Merge Factory
Free · Designed for iPad. Not verified for macOS.
Every tile carries +, −, × and ÷ at once. Tap to rotate them, drag to merge. 100 levels, each one solved by a solver before it shipped. No timers, no guessing.
Every tile is a number. Every tile is also four operations.
Look closely at one: it carries +, −, × and ÷, one on each of its four sides. Drag it upward and it uses whatever operation sits on its top edge, applied to the nearest tile above. Drag it left and it uses the one on its left. Double-tap, and all four operations rotate one step around the tile.
That single twist is the whole game. You are not hunting for the right direction — you are arranging the operations before you commit to them.
HOW TO PLAY
• Drag a tile toward a neighbour to merge the two into one result.
• The operation used is the one on the side you dragged from.
• Double-tap a tile to rotate its four operations one step clockwise. This costs a move.
• Empty squares never block the line. The nearest tile in that direction is always the one you hit.
• You win when exactly one tile is left on the board and its value equals the Target.
Two tiles left is a loss. The wrong final number is a loss. Everything has to come down to one.
100 LEVELS, EVERY ONE SOLVED FIRST
No level shipped without being run through a solver. The shortest solution is known for all 100, and the move budget is set deliberately above it — enough room to think, not enough room to flail. Nothing here is impossible, and nothing here is filler.
Boards open at five tiles and grow from there. Targets climb from 15 into the tens of thousands. The later levels ask for rotations that look wasteful until three moves later, when they suddenly do not.
BUILT FOR THINKING
• No timers. No countdown, no pressure, no penalty for putting it down mid-board.
• Undo anything you regret.
• Stuck? A hint plays the next move of a real solution, not a guess.
• Works offline, anywhere.
• One hand. Drag and tap — that is the entire control scheme.
If you like arithmetic that behaves like a spatial puzzle rather than a quiz, this is that.
