Replit Game Builder: Plan Around the 30-Day Link
Replit can act as a game builder: you describe the game, Agent writes it, and you publish it from your browser with nothing to install. On the free Starter plan your one public link goes down after 30 days, so plan your playtest around that date.
Details below come from Replit's docs and pricing page on 2 November 2026.
What does the free plan really give me?
- Daily Agent credits that reset each day, with a monthly cap.
- One free published app, with a "Made with Replit" badge.
- Lite build only. Full build needs Core or Pro.
Core costs $20 a month, or $18 on a yearly bill, and Pro costs $100, or $90 on a yearly bill. Replit's docs do not list the size of the daily allowance in the pages we read, so find out by using it.
Replit's docs show that games are a real use: one tutorial builds a retro-style game app called PixelGames with Agent and tries it in a preview that switches between iOS, Android and web. If you want the App Store, a separate guide says you need an Apple Developer Program membership. For a game among friends, a web link is much simpler.
Plan backwards from the day people play
The 30-day rule sounds harsh, but it only matters if you publish too early. Work back from the date you need the link.
Say you are making Bus Stop Bingo, an invented phone game. Each player gets a grid of things you might spot at a bus stop, and the first to mark four in a row wins. Eight friends will play it on a trip on 12 December.
| When | What |
|---|---|
| Mid-November, week 1 | Build in the preview, one feature a day, because credits reset daily |
| Week 2 | Play alone at phone size and fix what annoys you |
| 5 December | Publish. Send the link to two friends for a trial |
| 12 December | The trip |
| 4 January | The link goes down. Put it in your calendar |
That leaves a full week for a trial, at no cost. If the group loves it and wants to keep it, you can decide then whether Core is worth it. We could not find out from the docs whether publishing again resets the 30 days, so ask Replit before you count on that.
A game for several phones hides one trap: everyone can win at nearly the same moment. Have Agent draw a round first, in Mermaid, which is text that turns into a picture at mermaid.live. Agent runs the app itself, so it can then play the drawing through in its preview. To decide how far to take the idea, browse the topics.
Paste this to your AI
Plan Bus Stop Bingo, a simple web game for phones. Each player sees a 4 by 4 grid of things you spot at a bus stop, shuffled per player. Tapping a square marks it. Four in a row wins and shows a winner screen.
Before you build, draw one round as a Mermaid diagram: joining, playing, someone wins, the round ends. Check what happens if two players finish at nearly the same moment and if a player's phone locks mid-round. Show me the answer, then build from the diagram.
Keep it small enough for a Lite build, and tell me before you add anything I did not list.
Afterwards, open it in the preview at phone size and play one full round. Report what you tapped and what appeared. List every line that counts as four in a row, so I can compare them with the grid. Anything you did not actually do in the preview, mark "not tried".

How to check it worked
- Win three ways. Along a row, down a column and on a diagonal.
- Compare two phones. The grids should differ.
- Tap a marked square again. Decide what should happen, and see if it does.
- Open the published link on mobile data. Your home Wi-Fi can hide problems.
- Check the day count. Write down the date you published, plus 30 days.
