About this game

Merge Reactor is a 2048 style merge puzzle game with an elemental twist. Slide the 5x5 reactor board, merge matching energy cores, and chain combos to build the strongest core you can — a fast, free puzzle game you can play offline, anywhere.

HOW IT PLAYS
Swipe to slide every tile on the board. Cores with the same number merge and double, just like a classic 2048 number puzzle — but here every core also has an element. Combine red and blue cores to create purple, mix blue and yellow for gold, and use these elemental reactions to unlock stronger merges and bigger chain combos.

Watch the heat bar: every move raises the pressure. Push the reactor into overload to earn powerful bonus turns, but plan carefully — slag and stone tiles block your lanes until you clear them with smart purple merges.
