About Niche Shift

You merge sea creatures to climb the food chain in Niche Shift, a puzzle game that adds a survival twist to familiar tile mechanics. Start by combining plankton into krill, then krill into fish, working your way toward apex predators and the mythical Leviathan. Each swipe or merge counts as a turn, so you need to plan carefully.

The challenge comes from hunger. Predators at level three and above grow hungrier with every move you make. If you don't merge them in time to satisfy their appetite, they starve and become bones—dead tiles that clutter the board and block future matches. Balancing expansion against the needs of your existing creatures keeps every decision tense. Poki Games offers this strategic take on merging where building an ecosystem means keeping it fed.
