Letting AI write your trivia questions is how you ship a quiz that is confidently wrong.
AI is great at building the quiz game. It is bad at being right about the facts inside it.
What works: you write or paste the questions, AI builds the timer, scoring, and screens. Check every number and date. Cut any question with two defensible answers.
And ten questions is plenty for a first version.
How to make a quiz or trivia game with AI, with five prompts you can copy and how to add a leaderboard or a live room: play.fifthdoor.com/blog/make…
Your global all-time leaderboard is killing your game.
When the top 10 is out of reach on day one, nobody checks it again. A board only works if a normal player can win something.
What actually gets checked: daily boards that reset to zero, friends-only boards, per-mode boards, and the player's own rank shown even outside the top list.
And never save scores in localStorage. It works locally and fails in a sandboxed host.

The PS1 never died. It's hiding in a used car lot.
Not GT2 makes you pass license tests, hunt cheap rides, tune them, then throw them into 6-car grids for credits and prize cars.

The robots only need one road. Make it the longest walk of their lives.
Eight turret types, two upgrade paths each, five sectors to hold. Clear them, then flip any sector to endless and see how long your core lasts.

Your Claude Code game works. On your laptop. That's the problem.
A game nobody else can play is a demo. The last step isn't more features. It's a link you can send.
The loop that gets a small game from rough to fun: one change per message, lose on purpose, paste console errors instead of describing them, test on a phone early.
And skip localStorage for saves. It works locally and breaks in a sandboxed host.

Hex map. Rival factions. One capitol left standing.
Muster the troops, keep the supply line alive, then take their strongholds before they take yours.

Your colony isn't cute. It's an arms race under the dirt.
Twenty gardens. Rival nests that raid. An evolution tree that splits foraging from defense, then unlocks scouts, army ants, royal guards.

"Free AI games, no download" is mostly a trap. Half the results want an APK from a random site. The other half are chatbots.
No download should mean one thing: open a link, play in the tab.
The quick test for any "no download" AI game:
1) Opens from a URL, starts in the browser
2) Real controls (tap, keys), not only typing prompts
3) More than one game to try next
4) Shareable link if you like it
Sideloading an unknown APK fails all four.
Fifth Door Discover runs in the browser on desktop, Android, and iPhone. Android also has the official Play Store app if you want an icon.

Your first AI game isn't too small. Your idea is too big.
Nobody finishes an open-world RPG in one session. People finish a balloon you keep in the air by tapping. Then they send it to a friend.
Four questions before you build: Can you say the goal in one sentence? Is there one core action? Is there a way to lose? Can a round end in under three minutes?
Pass all four and it's a good first build. Ambition is version two.

Your Wordle clone isn't failing because of the puzzle. It's failing because the puzzle changes when someone reloads.
A daily game is five rules: one shared puzzle, a fixed reset, limited tries, a spoiler-free share, and a reason to come back. The puzzle can be tiny.
Pick today's puzzle from the date, not a random roll, so everyone on the same day gets the same answer. Then change the theme instead of copying a famous game.
One sport, one fandom, one city. Niche dailies get shared.
