Merge and Double is a number-merging puzzle from Adgard. The board fills with tiles carrying small values, and your job is to spot two matching neighbors and combine them into one tile worth double — building toward bigger numbers one merge at a time.
There's no timer forcing your hand, so a session is really about reading the board: which pairs are sitting next to each right now, and which merge sets up a bigger one a few moves later. Power-ups are on hand to clear clutter or push your score higher when the board gets tight.
Controls

A good fit if you like calm, single-screen number puzzles in the vein of 2048 — something to chip away at for a few minutes without any pressure to rush.
