About Fintopia

Fintopia is an aquarium shop simulation that you play in a web browser. You take over a shop on the edge of a harbour, starting with a single reef tank, a key and one egg. From there you hatch fish, keep them fed, sell them to neighbours who leave orders at the counter, and open more aquariums as the shop earns coins and gains levels. Fish in Fintopia never die: a fish that goes without food for too long becomes sick, and one meal brings it back to health.

The game is free to play on Smaz Games. It runs in the browser on computers, phones and tablets, with no download and no in-app purchases. Coins are the only currency, and they are earned in the game.

How to play

  1. Name your shop and choose a shopkeeper. A short opening scene introduces the harbour, and you can watch it again later from Settings.
  2. Follow the opening lesson. It walks you through placing an egg, hatching it, feeding the new fish, collecting coins, cleaning algae and making your first sale. A second part covers caring for a fish, selling to your neighbour Mia, a fishing trip, and raising and breeding pairs of sardines and clownfish.
  3. Buy eggs from the Store, under the Fish tab. A bought egg hatches after a few seconds, and tapping it gives it a nudge.
  4. Feed your fish when they get hungry. Newly hatched fish arrive hungry, so feed them straight away.
  5. Let fish grow through four stages: Baby, Junior, Adult and Prime. Each species grows at its own pace, and a fish only grows while it is healthy.
  6. Sell fish or keep them. Open a fish's card to choose Sell or Keep, or fill a customer order at the Orders counter for extra coins.
  7. Spend coins on more eggs, decorations, tank space and new aquariums, and pay the daily power and water bills for each open tank.

Controls

Fintopia uses the same actions with a mouse or a finger.

Feeding, hunger and sickness

Each fish shows how well fed it is. A fed fish becomes Hungry after a while, then Starving, and finally Sick if it is left without food. The time between meals depends on the species and grows longer as the fish matures; a Prime fish can go a full day. Sickness pauses growth but never kills a fish, and a single meal cures it. Caring for a hungry, starving or sick fish also earns a small amount of experience.

Food is free for the first ten minutes of play. After that, each scoop costs one coin, or you can buy a food sack, which works out cheaper per scoop. Hand-fed nibbles cost nothing. Once you reach level 5, a Feed all button feeds every fish in the tank at once.

Customers and coins

Neighbours leave notes at the Orders counter asking for a particular species, usually at Junior stage or older. Up to three orders can be open at a time, and each has a due day. Serving an order pays the normal sale price plus a bonus that grows with your shop rating, and you can skip a note you do not want to fill. Some regular customers have short stories that continue across several orders.

Coins also come from ordinary sales, coin bubbles made by happy Adult and Prime fish while you watch, cleaning algae, goals, achievements, level-ups and a free daily spin whose odds are shown. Sale value rises with each growth stage, so a Prime fish is worth far more than a Baby. A rare colour sells for more than the classic one.

Tanks and decorations

The shop has twelve aquariums. Before you open one, it is listed by its habitat, such as the reef, glow cave, freshwater pond, mangrove, kelp forest, shipwreck, polar and deep trench tanks, with later tanks including Kelp Tower, Jelly Lagoon, Koi Garden and Giant Ocean. Each needs a certain shop level and a number of coins. The freshwater pond is always the second tank, and it opens on Day 3 or at level 4. Opening a tank gives you an egg of a fish that lives there. Every tank starts with room for 25 fish, and you can expand it to 40 and then 60; eggs count towards that space.

The Store's Decor tab sells twenty decorations, including seasonal pieces and items that suit a single tank, such as water lilies or a ship's wheel. Drag a decoration along the sand and choose Place here. In Edit mode you can move, flip, store or sell it, and resize it between 60% and 150%. The plants in each tank are part of the background and cannot be moved.

Tips for new and experienced keepers

Saving your shop

Fintopia saves on its own every few seconds, after important actions and when you close or hide the tab. On Smaz Games the save is kept in your browser on that device, so it does not move to another device and is removed if you clear your browser data. This game does not use Smaz Games account saves. When you come back, the shop works out how long you were away and shows a summary.

Devices and screen orientation

The game works with a mouse or by touch, and has layouts for both portrait and landscape.
