Sell a Million Sushi is a free-to-play Roblox experience where you run a sushi restaurant and try to make it the most profitable one on the server. Your job is to manage the restaurant’s supply and cash flow so the business keeps running. The faster you grow your fishermen, the faster your money climbs.

The game is built around a loop that is easy to pick up. Players hire fishermen, collect fish, deposit the fish at the cooking station, and then collect the money. Every other mechanic exists to serve that loop. As you progress, you unlock new fish species to serve and better fishermen to supply them.

How the core loop works

Each of the four steps works in a way similar to tycoon-style games. You step on buttons to carry out actions, which keeps the game free of heavy menus. Once you have enough Cash, you can hire additional fishermen and buy upgrades that improve your cash flow.

That simplicity is the reason the game is easy to start. There is little to memorize at first. You just keep the loop running and reinvest the money you earn.

Controls you need to know

Movement uses W, A, S, and D. Jump is the Spacebar, and the Interact key is E. Most actions in the game are triggered by stepping onto buttons, so you will spend more time walking around the restaurant than pressing keys.

Merging fishermen is the key to progress

Fishermen can only catch one type of fish. That limit is why merging matters so much. Once you hire three fishermen, you can merge them into a single fisherman who catches fish of a higher rarity.

The process is incremental. Three tier 1 fishermen merge into one tier 2 fisherman. Three tier 2 fishermen merge into one tier 3 fisherman, and the chain continues from there. The highest fisherman tier is 24, so reaching the best fisherman means hiring dozens upon dozens of them.

You do not directly choose which fish you get outside of merging. If you want rarer fish, your best lever is building up fishermen and merging them. Rare species are the path to higher cash flow, and the guide’s central advice is to chase them.

Try to unlock the rarest fish species to maximize your overall Cash flow and become the most profitable Sushi restaurant on the server.

Upgrade your chef, but do not obsess over it

You can also upgrade your chef to generate more Cash per second. Step on the button next to the chef’s station, and the upgrade improves how quickly the chef serves customers.

Chef upgrades matter less than fisherman merging for your overall Cash generation. Check on them every so often, but put most of your early money into hiring and merging fishermen.

Batch-hiring for late-game speed

Once your cash generation is high enough, you can hire fishermen in bulk. Batch-hiring lets you instantly merge them into high-tier options. Merging automatically moves fishermen into the highest tier they can reach.

Here is a concrete example from the game’s mechanics. If you hire 12 fishermen and press the Merge button, you get one tier 3 fisherman instead of three tier 2 fishermen. That shortcut can speed up progression a lot in late-game play, since you skip the intermediate steps.

The practical takeaway is to scale your hiring as your cash allows. Hire in bigger batches once you can afford them, then merge, so your roster jumps tiers instead of crawling through each one.

Is it free, and how do you merge?

Sell a Million Sushi is free to play, though it includes optional premium purchasable elements. You do not need to spend money to progress through the core loop.

To merge fishermen, step on the Merge button while you have three or more fishermen of the same type. The merge only works on matching types, so keep your roster organized as you hire.

A quick plan for new players

Start by hiring fishermen and keeping the four-step loop running. Collect cash steadily and reinvest it. When you have enough fishermen of the same type, merge them. Upgrade your chef now and then, but treat it as a secondary priority. Once your income is strong enough, switch to batch-hiring so your fishermen reach higher tiers faster.

Sell a Million Sushi rewards patience and planning more than fast reflexes. The players who climb fastest are the ones who understand that merging drives everything else. Build your fisherman tiers, unlock the rarer fish, and your restaurant will move from a small counter to the top of the server.
