Roll & Merge

Roll a sticky ball through a living isometric world — and roll it ALL up. Start tiny in the backyard, sweeping up pebbles and acorns. Match two of the same thing on your ball and they MERGE into something bigger. Grow past cones, bushes and benches, swallow trees and cars, roll entire houses into your ball downtown, then keep climbing into a glittering dusk skyline where stadiums and towering landmarks are just more things to absorb. HOW IT WORKS • Drag to roll — one thumb, no buttons • Anything smaller than your ball sticks to it • Two matching objects merge into the next bigger thing • Bigger object types unlock as you vacuum up more stuff • Fire, bombs and spikes SHRINK your ball — steer around them • Reach full size at the top of the Skyline to finish the run FEATURES • Five escalating stages in one continuous run: Backyard, The Park, Suburbs, Downtown, and Skyline • A camera that pulls back as you grow — feel the scale • Hand-crafted isometric world with day-lit lighting, shadows, and a dusk-lit downtown finale • Longer runs with more to climb toward • Beat your best score and roll further every time Free to play. An optional one-time purchase removes ads between runs.
