Verdict

The call

The clearest difference is ads: Roblox at none against Mortal Kombat's shown. Roblox also leads on update cadence (weekly vs every 3 months) and ratings volume (20M vs 151K). On price, rating, review sentiment and in-app purchases there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. Roblox sells 16 in-app purchases, starting at $4.99 per month and Mortal Kombat sells 13 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

On the App Store both sit at effectively the same score — 4.5 for Roblox against 4.5 for Mortal Kombat. That said, the two scores are not equally well evidenced: Roblox has 20M ratings behind it against 151K, so its average is the more settled of the two. Written reviews are what separate them: 60% of Roblox's written reviews are positive against 54% of Mortal Kombat's.

UpkeepUpdate frequency

Roblox ships an update weekly, Mortal Kombat every 3 months. Both last shipped on September 24, 2026.
