** Apple Design Award winner and iPad Game of the Year! ** Enter the Darwinian world of a galactic mote. To survive, absorb smaller organisms and grow—but beware of larger predators. Osmos features unique physics-based play, stellar graphics, and a hypnotic ambient soundtrack. Absorb or be absorbed! “The ultimate ambient experience” — Gizmodo “Beyond doubt, a work of genius" — GameAndPlayer.net THE CRUX: you must grow by absorbing smaller motes, but to propel yourself you must eject matter behind you, causing you to shrink. From this delicate balance, Osmos leads the player through floating playgrounds, competitive petri dishes, deep solar systems, and more. “Named as iPad Game of the Year for a reason, Osmos is a fantastic game.

Instead of paper, pen, and doing the math, you just enter your rolls on your phone — the app handles subtotals, bonus, and your total score automatically.

No more miscounting — just focus on rolling. - For the whole group: Up to 5 players take turns on a single device. You can always see whose turn it is and who's in the lead. - Always with you: Your phone's already in your pocket — all you need on top of that is a few dice. Perfect for on the go, on vacation, or a spur-of-the-moment game with friends. - Good for the planet: No paper, no scribbled-up score pads. Game after game, zero waste. HOW TO PLAY Up to three rolls per turn, then pick a category and enter your score. After 13 turns, the winner's decided — no recounting needed. Grab the dice and get rolling.

Verdict
The clearest difference is price: RollUp at Free against Osmos's $3.99. RollUp also leads on update cadence (every 2 months vs every 7 months). Osmos's advantage is chart position (#92 vs unranked) and device support (4 vs 1). On ads and in-app purchases there is nothing between them.
