Frequently Asked Questions

How do I play?

Slide colored blocks on the grid to clear a path for the red target block to reach the exit. Tap and drag a block in its allowed direction — horizontal blocks slide left and right, vertical blocks slide up and down. Each slide counts as one move. Solve the puzzle in as few moves as possible to earn 3 stars.

How does the daily puzzle work?

A new puzzle is available every day in three difficulties: Quick, Standard, and Expert. Every player around the world receives the same puzzles. Complete at least one daily to maintain your streak. Your streak tracks the number of consecutive days you've completed a daily puzzle.

What is the par score?

Par is the minimum number of moves needed to solve a puzzle. Solve at or under par for 3 stars, within par + 5 for 2 stars, and any other solve earns 1 star. You can replay any puzzle to try to beat par.

What are linked blocks?

Linked blocks are two blocks connected by a chain. When you move one, the other moves in the same direction simultaneously. If either block is obstructed, neither can move. They're introduced in Campaign Chapter 3.

What are the special block and cell types?

The campaign introduces new mechanics chapter by chapter:

How do hints work?

You receive 3 free hints each day. A hint highlights the next block to move and shows the direction. Once your free hints are used, you can watch a short video ad to earn 3 more. Hints are not available in Weekly Challenge, Versus Duel, or Blitz mode.

What does Remove Ads include?

The Remove Ads purchase ($2.99) permanently removes all interstitial ads. Rewarded ads for hints and bonuses remain available as an optional choice. The Remove Ads + Unlimited Hints upgrade ($4.99) also removes the daily hint cap entirely.

How does Co-op multiplayer work?

One player creates a room and gets a 6-character code. Share the code with a friend. Each player controls different colored blocks on the same board — Player 1 controls red and orange, Player 2 controls blue and green. Gray blocks can be moved by either player. Work together to free the target block.

How does Versus Duel work?

Both players receive the same puzzle simultaneously and race to solve it first. You can see your opponent's progress as a percentage bar, but not their actual moves. The first to solve wins. If both solve, the player with fewer moves wins.

How does Blitz mode work?

Solve as many puzzles as possible in 3 minutes. Puzzles start easy and get harder every 3 solves. Your score is based on the total stars earned. Watch an ad for +30 seconds (once per run). Compete on the weekly Blitz leaderboard.

How does the Weekly Challenge work?

One large puzzle resets every Monday at midnight UTC. No hints allowed — pure skill. Players are ranked by fewest moves, with time as a tiebreaker.

How do I unlock themes?

Themes can be unlocked in several ways: watching a short video, reaching a campaign star milestone (50, 150, or 300 stars), or earning them through gameplay. All themes are free — no cash purchase required.

How do I sync my data across devices?

Your data syncs automatically via your account. If you sign into Game Center on a new device, your progress, hints, and unlocks carry over. Without Game Center, your data syncs per-device.

How do I restore my purchases?

Go to Settings inside the app and tap "Restore Purchases." This will restore any previous purchases tied to your Apple ID. Make sure you're signed in to the same Apple ID you used for the original purchase.

How do I connect to Game Center?

Game Center connects automatically when you open the app, as long as Game Center is enabled on your device. Go to iPhone/iPad Settings > Game Center and make sure it's turned on and you're signed in with your Apple ID.

My game progress was lost. Can I get it back?

If you were signed into Game Center, your progress can be recovered on any device by signing into the same Game Center account. Without Game Center, progress is stored locally and cannot be recovered after uninstalling.

I found a bug. How do I report it?

Please email us at puzzlespark@protonmail.com with a description of the issue, your device model (e.g., iPhone 16, iPad Air), and your iOS version. Screenshots are very helpful.
