Machh Chash is a free idle fish farm that you can play online in your browser with no download. Last year's flood washed every fish out of Sohel's family ponds, and with the help of Nasrin Apa, the fisheries officer, he is going to build the farm up again.
Tap the ponds to release fingerlings and watch them grow. Every fish adds a little to the harvest each second, but only what your rickshaw vans, pickups and lorries carry reaches the market, so the ponds and the fleet have to grow together. Study new ideas, build a hatchery, an embankment against the monsoon floods and a medicine shed against fish disease, and farm six species, from rui and katla all the way to giant river prawns.
For more idle tycoon games, try Brick Field, an idle factory tycoon, or Launch Ghat, a river port tycoon.
Yes. Machh Chash is free to play in your web browser, with nothing to download, install or buy. Every pond, vehicle, research idea and species is free. Coins exist only inside the game, and signed-in players also earn GamesYap points as the farm grows and for three achievements.

Yes. The game runs in the browser on phones, tablets and computers, upright or sideways. Tap the ponds to release fingerlings, use the buttons to buy and treat the fish, and switch between the farm, fleet and research with the tabs at the bottom. On a computer you can also press Space.
There are two limits. The ponds only have room for so many fish, and the fleet can only carry so many kilos a second. When the fish badge is full, widen the ponds. When the fleet badge drops below 100%, buy more vans, pickups or lorries.
In every monsoon a flood comes, and a minute before it arrives the game shows its strength. An embankment at least that high keeps every fish safe. A lower one lets some fish swim out with the flood water, so raise the embankment as the floods grow stronger.
When you move on to the next species, the ponds, fleet and research start again, but you keep your Know-how. It comes from all the coins you have ever earned, and each point makes the fish grow faster and every handful of fry bigger, for good.
