Redlight Greenlight questions

What is Redlight Greenlight?

Redlight Greenlight is an Android app by Sonicon Software with mini games for one shared phone. Two players can play on the same screen, or one player can take on Robo, the built-in bot, at Easy, Normal or Hard. It has no ads, no accounts and no in-app purchases, and it doesn't use the internet.

Can two people play on one phone?

Yes. Choose "Play with a friend" in any game except Flappy Race, the one solo-only game, and both players use the same phone. Action games such as Air Hockey, Tank Battle and Dig Race split the screen so you play at once; board games such as Connect Four take turns.

Can I play alone?

Yes. Most games start against Robo, the built-in bot, at Easy, Normal or Hard. Flappy Race is a solo run, and Merge Race starts as a solo game where you aim for the 2048 tile. Solo runs keep your top score for each game.

Is Robo hard to beat?

Robo has three levels. Easy makes more mistakes than Normal, and Hard is tuned so a good player can still win. The app's tests check that a well-played opponent beats Hard Robo in every game where skill decides. Wins against Robo raise its rank at that level, from Rookie to Legend.

Does it work without internet or Wi-Fi?

Yes. Redlight Greenlight doesn't request Android's internet permission, so every game, Robo and Today's Race work with no connection at all. There is no online play: both players use the same phone. Your progress is kept in the app's storage on that phone.

Are there ads or in-app purchases?

No. The app contains no advertising, no analytics and no in-app purchases, and there is no account to create. It is free to download from Google Play. Rewards such as stickers, levels and avatar looks are earned only by playing, never bought.

What data does Redlight Greenlight keep?

Only what the games need: player names and avatars, levels, stickers, the daily streak, scores, Cup results and settings. They stay in the app's private storage on your phone. The app has no internet permission, so it can't send them anywhere. The privacy policy has the full list.

How do I reset scores or start over?

Open your profile and choose Reset scores. It clears wins, games played and Cup history, while names, looks, levels and stickers stay. To remove everything, clear the app's storage in Android settings or uninstall the app. Both delete all its data from your phone.

Is there a Red Light, Green Light game in it?

No. Redlight Greenlight is the app's name, taken from the schoolyard game. The traffic light is how you start: tap the green light and the game begins. The games are board classics and action duels, from Tic-Tac-Toe and Ludo-lite to Air Hockey and Dig Race.

What are Today's Race, the Cup and stickers?

Today's Race is one game a day with a small goal; finishing it grows your streak. The Cup is a run of 3, 5 or 7 random games where the overall winner lifts the cup. Stickers are rosettes for firsts, such as your first win in each game, and fill a sticker book.

What is Diyas?

Diyas is a lamp-lighting game. Gusts of wind blow the lamps out; tap a dark diya to light it again, and keep more lamps burning than Robo or your friend, first to two rounds. Around Diwali the court adds a marigold garland and a fuller rangoli.

This year the Diwali decoration shows from 5 to 12 November 2026.

What is Dig Race?

Dig Race is a race to uncover a fossil. Each player rubs the rock off their own slab, and the fossil's faint outline shows from the start, so you know what you are digging for. Uncover all of it first to take the slab; the first to two slabs wins. Play it against Robo or a friend.

If nobody uncovers the whole fossil within 40 seconds, the bigger dig takes the slab; an even dig goes to nobody. A match ends after five slabs at most.
