A grid of pictures on a clean board. Two of the same slide together and become the next picture up, the empty cells refill, and the climb goes on until one final picture is left.
Grid Merge is a merge chain with nothing in the way. Pictures sit in the cells of a grid, two of the same slide together, and on the frame they meet they become the next picture in the chain. Pieces keep their size, so the story is the picture changing, not the piece growing.
Every phase merges down to one piece in the middle. Then the cells around it refill row by row and the climb carries on, so the run always ends the same way: one final picture alone on the board.
Every merge and every refill plays its own sound. The small merges trade two notes back and forth, the big ones step higher, and the last merges climb the whole ladder to the final form.
Equal pieces that sit next to each other merge, one sliding onto the other in a single move. The whole run is planned so the next twin is already next door, and the biggest piece stays in the middle of the grid.
A merge changes the picture and leaves the size alone, so a full grid and an empty one read the same way. Size growth per merge is there if you want it.
Every phase ends on one piece in the middle. Only then do new pieces fill the cells around it, row by row by default, and the merging starts again.
New pieces start bigger in each later phase, so the count is always exact. A chain of six takes three phases and 23 merges, and lands on one final form with nothing left over.
The default three by three grid fills a square video. The grid fits every video shape.
Each extra piece adds one phase to the run. The grid needs at least one cell per piece.
A steady slide with a short rest between merges keeps a clean rhythm.
New pieces arrive only when one piece is left in the middle.
Every merge has its own row, where you can pick a sound from the library or upload one.
The board keeps emptying and refilling around bigger and bigger pieces, and viewers stay to see what the last picture is.
One note per merge turns the run into a small melody that repeats and climbs, which is easy to keep watching.
Nothing but the pictures on a plain board. It reads at a glance, even on a small screen with the sound off.
The last merges slow down and step up one by one, so the ending is felt coming.
One cut-out per piece, such as a pet, a character or a product, merging up to the one you want to finish on.
An egg to a parrot, a seed to a tree: a chain people recognise without any explanation.
Numbers that double with each merge, for a 2048 style climb on a real grid.
A square video with the grid filling the frame, or a vertical one with the grid across the middle.
Six pieces run about 25 seconds on the defaults, and each extra piece adds about 9 seconds.
Choose your images smallest first and put the whole group on the chain in one tap.
Square fills the frame with the grid. Vertical leaves room for a title above it.
Keep the defaults, or give any merge a sound of its own from the library or an upload.
Generate a seed for the clip length you want, and the run lands the final form on that second.
With no physics to watch, all the attention goes to what the pictures become. Each merge is one clear step, on a steady beat, and the viewer always knows what is about to happen next without knowing how the chain ends.
The refills are what keep it going. Just as the board empties, it fills up again around the pieces already earned, so progress stays on screen while the work starts over.
