Which one to pick
Pick Castle if
You like building a game piece by piece. Castle's editor covers art, physics, logic, music and sound, with templates and remix. It is on Android today, it has parties and multiplayer, and its listing says the feed has zero ads.
Pick Roam if
You are on iPhone and want the game without the editor. Type one sentence, play it, and friends can be in the game with you. Roam has no Android app yet, so Castle wins on Android.
Pick Loopit if
You want small AI playables from a typed idea, in a swipe feed where others can remix your work.
What Castle does well
Castle - Make and Play has been on the App Store since February 2021. Its listing calls it social media for creating and playing games: make a game, share it with friends or the community, follow creators and chase high scores.
The editor is the core. It has tools for art, physics, logic, music and sound, a library of game objects, and templates. Creating and sharing never needs a purchase. Castle's terms also describe a Creator Payout Program for eligible creators. Google Play shows 10M+ installs.
Castle vs Roam: building by hand or describing it
The two apps answer different wishes. Castle is for people who want to build: place objects, set rules, draw the art. Roam is for people who want to play the idea now. Describe the game in a sentence, or start from a photo, and it comes back playable. Then change it by talking: "more enemies", "make it two-player". No code, no engine, no project files.
Both put friends in the picture. Castle's App Store update notes mention parties and multiplayer. On Roam, you play solo, or friends join and can be in the game. Roam is on iPhone and iPad, with no Android, web or PC version. Castle is on iPhone, iPad and Android.
Castle's editor next to Loopit's prompts
Castle is editor-first: you build by hand, from a blank scene or a template. Loopit is prompt-first: its AI builds a playable from a typed idea. Our Loopit vs Sekai vs Aippy vs Castle comparison covers their feeds, costs and terms side by side.
