Standalone Mobile Games vs Roblox
Short answer. A standalone mobile game gives you the gameplay without the platform. You gain a small install that opens straight into a level, no account, offline play and a single content rating that describes the whole product. You give up the endless supply of player-made levels, the shared avatar, friends and sessions. Whether that is a good trade depends on which of the two you were actually there for.
Disclosure. Brainytrainee Ltd publishes the games listed on this site. This article is written by the publisher, not by an independent reviewer — where it names our own games, treat that as what it is. Games from other studios are included because leaving them out would make the comparison useless, and we do not receive anything for mentioning them.
How we put this together
This guide compares two product models — a standalone game and a user-generated platform — rather than ranking titles. Games from other studios are named where they are the honest answer for a category we do not compete in; we have no commercial relationship with any of them and receive nothing for listing them. Facts about our own games come from the live store listings, verified 13 August 2026. We do not rank our own games above other studios' games, because a publisher ranking itself first is not a ranking.
The two products are not substitutes for each other
Before comparing anything, it helps to separate what people are usually after. The phrase covers at least four different wants, and they point in completely different directions:
1. The obby courses. You want obstacle-course platformers — run, jump, fall, retry. This is the most common meaning and the easiest to satisfy outside a platform.
2. The pet, life and roleplay sims. You want to look after something, decorate a space, or play a role. Also well served by standalone games.
3. The building. You want to make things, not just play what someone else made. Partly served — by sandbox games and by level editors inside other games.
4. The platform itself. You want thousands of experiences made by other players, a shared avatar, friends and sessions. This one has no standalone equivalent, and pretending otherwise wastes your time.
If you want the obby courses
This is the straightforward case. Standalone obby games are published on both mobile stores and play the same way: platforms, timed hazards, close checkpoints, instant retries. No account, no login, and the core levels run offline.
Ours are Mega Obby, the larger one with several modes and a sandbox level editor, and Prison Escape, a tighter timing challenge around guard patrols and lasers. Both free, both on iPhone, iPad and Android.
They are not the only ones — search the platformer category on either store and you will find plenty of standalone obbies from other studios, with the usual caveat that quality varies and copycat listings are common. Check the publisher name, not just the title.
If you want the pet, life and roleplay sims
Also well covered, and mostly by studios other than us. The pet-care corner is crowded on both stores; the life-sim and roleplay corner is dominated by long-running series such as Electronic Arts' The Sims mobile titles and the many dress-up and household games around them.
Our two are pet care specifically: Talking Dog, listed on Google Play as Virtual Pet Simulator - Archie, and Cat Simulator, which is currently iPhone and iPad only. The virtual pet games page compares them.
If what you want is roleplay with other people rather than caring for an animal on your own, we do not make anything in that space, and none of our games is the answer.
If you want to build
Building splits into two different desires. Building a world — terrain, structures, systems — is Minecraft's territory, and Mojang's mobile version remains the obvious answer; there is no point pretending a level editor competes with it.
Building a course is narrower and better served by editors inside obby games. Mega Obby's sandbox mode gives you the same block set its built-in levels use, so you lay out platforms, traps and checkpoints and then run the result. What you do not get is other people playing what you built, which for many players is the actual appeal.
If you want the platform, be honest about it
If what you enjoy is that thousands of other people keep making new things, that your avatar and its cosmetics follow you everywhere, and that your friends are in there — no standalone mobile game provides that. The closest structural equivalents are other user-generated platforms, not individual games.
This is the part where an article written by a game publisher is supposed to steer you toward its own catalogue. We would rather say it plainly: our games cover two genres well, and they are not a platform. If a platform is what you want, install a platform.
A note on downloads
Searches in this area surface a lot of APK sites and "unlocked" versions. Install from the App Store or Google Play only. Third-party APKs skip store review, are frequently modified, and are a common adware route on Android. Every link on this site points at an official Apple or Google listing.

Frequently asked questions
Is there a mobile game exactly like Roblox?
No. Roblox is a platform hosting experiences made by other players, not a single game. Standalone mobile games can cover individual genres from it — obby courses, pet sims, building — but not the platform itself.
What are the best mobile alternatives for obby games?
Standalone obby platformers on the App Store and Google Play. We publish Mega Obby and Prison Escape; other studios publish plenty more in the same category.
Are there games like Roblox that do not need an account?
Yes. Standalone mobile games install and play without any platform account. That is the main practical difference between a standalone game and a platform.
Is Minecraft like Roblox?
They overlap on building but differ in structure: Minecraft is a single game about building and surviving in a world, while Roblox is a platform hosting many games made by its users.
Obby Games
An obby is an obstacle course you run on foot: platforms, gaps, moving hazards and a finish line. Brainytrainee publishes two of them for iPhone, iPad and Android — Mega Obby and Prison Escape — and both install as ordinary mobile games with no Roblox account involved.
