Shipwrecked on a quiet tropical island, the castaways need a hand. Tap the generators to make shells, wood, fruit and camp supplies, then drag two matching items together to merge them into something better.
Serve the islanders walking along the shore to earn coins, then spend them in BUILD to repair the camp, dock, cabins and lookout. Eight zones open one by one, each with new item chains, orders and a little more of the island brought back to life.
How to play & tips
How to play
- Tap a lit generator to drop a new item onto the board.
- Drag one item onto an identical item to merge it into the next tier.
- Watch the order bubbles above the islanders; drag the finished item to a customer, then press GIVE.
- Merging and serving use energy; it refills over time, and the daily gift tops it up.
- Spend coins in BUILD to restore each zone and unlock the next stretch of the island.
Tips
- Keep one of every item you have unlocked; an order can ask for any of them.
- Serve the smallest order first to free a board slot and keep customers moving.
- Do not tap the generator with a full board - merge or sell first.
- Clear the daily gift and free gem timer before a longer session.
- Build the next zone as soon as you can: new zones bring new item chains and better orders.
