How can we help you?

Yes — every world's weekly puzzle is completely free to play. Optional in-app purchases ($4.99 to unlock one world permanently, or $1.99/month for unlimited access to every world) let you jump into any world at any time, but the free tier always includes one playable world per week.

You can explore Quiblo without signing in, but creating a free account lets you save your progress, appear on leaderboards, and track your eco-points across sessions.

Tap Create account on the home screen. Enter an email address and choose a pilot name — that's it. No personal information beyond your email is required.

Eco-points are earned by completing puzzles and solving challenge pieces. They appear on the all-worlds global leaderboard. In future updates, eco-points will be redeemable for badges, tree-planting donations, and physical prizes.

Each world (Coral Reefs, Ancient Forests, Frozen Tundra, Golden Savanna…) gets one fresh puzzle every Monday at midnight UTC. Pick a world, solve any mini-puzzles to unlock challenge pieces, then drag every piece into place on the 8×6 grid. Puzzle tabs and blanks must match — just like a real jigsaw.

Some jigsaw pieces arrive "damaged" and shatter into smaller fragments. Before placing them on the main grid, you reassemble the fragment mini-puzzle. Completing it reveals a real ecology fact about that ecosystem.

Each world's leaderboard ranks players by fastest completion time for the current weekly puzzle. In the event of a tie, higher puzzle accuracy (fewer misplaced pieces) breaks it. You can replay the same puzzle as many times as you like — only your personal best time is shown.

Yes, as many times as you want. Replaying is encouraged — learning the layout lets you shave seconds off your time and climb the leaderboard. Only your fastest time per puzzle is saved.

New puzzles roll out every Monday at midnight UTC. All worlds update simultaneously, so there's always something new each week.

Quiblo currently features four worlds: Coral Reefs, Ancient Forests, Frozen Tundra, and Golden Savanna. More ecosystems are on the way.

A one-time $4.99 purchase unlocks full access to one world's weekly puzzle — permanently. You'll be able to play that world's puzzle every week, forever, with no further charges.

The monthly subscription unlocks every world simultaneously, every week, plus access to the global all-worlds leaderboard. It auto-renews monthly and can be cancelled at any time through your Apple ID settings.

Tap Restore Purchases on the pricing screen — this re-syncs your entitlements from Apple. If the problem persists after restoring, please email plutosjt@gmail.com with the email address linked to your Apple ID and we'll sort it out.

Yes. Quiblo has no in-app chat, no social features, and no third-party advertising. A parental gate (a simple grown-up maths check) is required before any purchase, any external link, and any account deletion. We comply with COPPA (US) and GDPR-K (UK & EU).
