Pour soft jellies into a jar. Two identical ones merge into a bigger one. Keep going as long as you can — the jar fills faster than you think. Colour tells you the family, size tells you the level. Nothing to memorise: if two jellies look the same, they merge. Gloop is built around one thing: how the jellies feel. They squash against each other, roll, settle and wobble, all simulated. Tilt your phone and the whole pile leans. • A colour bomb falls through the pile and blows up a whole cluster of its own colour — steer it on the way down • New colours appear as you score, and that is what makes it hard • The landscape shifts with your score: dawn, storm, desert, deep sea, nebula • Sound is entirely synthesised — even the wind chimes on the title screen • No ads, no accounts, no timers, nothing to buy Play for thirty seconds or thirty minutes. It waits.

Verdict

The call

The clearest difference is review sentiment: Gloop Jelly at 100% against Knock Out's 50%. Gloop Jelly also leads on rating (5.0 vs 4.8) and monetization model (ad-supported vs free with in-app purchases). Knock Out's advantage is ads (none vs shown) and ratings volume (38K vs 1). On price, in-app purchases and device support there is nothing between them.
