Common questions

How do I play?

Place flowers so that every row, every column, every colored region and — on larger boards — both large diagonals contain exactly one flower of each color. Tap a cell once to mark where a flower cannot go, double-tap to place a flower. The in-game How to play guide walks you through a real level step by step.

Does the game need an internet connection?

No. Every puzzle ships inside the app, so it plays the same on a plane as it does at home. An internet connection is only used for ads, purchases, and optional Play Games / Game Center sync.

Do I need an account?

No. The game never asks you to register, and it works fully without signing in to anything.

What are the suns?

Suns are the game's currency for hints. You earn them by playing: a free daily gift, level rewards, and optionally by watching a rewarded ad. You can also buy sun packs with real money if you want to support the game - but nothing requires paying; every level is solvable with the suns you earn.

What does a hint do?

A hint (the lightbulb) highlights a cell where a flower can definitely go right now. The dots power-up (the ··· button) marks all cells a placed flower blocks for the rest of the level - it costs one sun per level and stays on for that level.

I lost my progress after reinstalling

Progress is stored on the device, so uninstalling the app removes it. Signing in to Play Games (Android) or Game Center (iOS) keeps a copy in the cloud, which is restored automatically the next time you sign in on any device.

I bought suns but did not receive them

Purchases are delivered the moment the store confirms them, and the delivery is remembered so it can never be lost. If a purchase is still missing, fully close and reopen the app - pending store confirmations are completed on launch. If that does not help, email us with the order number from your Google Play / App Store receipt.

How do I restore a purchase on iPhone?

Open the sun shop (the sun counter), scroll to the purchases section and tap Restore purchases. The Remove Ads product is restored automatically this way; suns are delivered instantly at purchase time and do not need restoring.

How do I delete my data?

Uninstalling the app removes everything stored on the device. To remove a cloud save, delete the game's saved data in the Play Games or Game Center app. Details are in the privacy policy.
