Play The Fish Game

Play Online

You have 10 days to fish. The money you make from these fish will need to support your family for the next month. Each fish nets $2.

Each day, you'll choose whether you want to take none, one, two, or three fish for the day. There are two other fisher folk also trying to catch as many fish as they can - they will follow your lead, and base their catch on yours.

The lake in which you are fishing can only support 20 fish (that is the carrying capacity of the lake). Every night, the fish that remain after a day of fishing will reproduce at a rate of 25% (for the purpose of this game, we round to the nearest whole number). However, the total number of fish can't exceed 20. For instance, if there are 12 fish, they will multiply to 15 overnight. If there are 19, they will multiply to 20.

Ready to play? Remember: the object of the game is to have as many fish as possible at the end of the game.

Help Us Upgrade The Fish Game Online

The Cloud Institute uses The Fish Game to start the conversation about education for sustainability with students and stakeholders. The simulation invites us to 'go fishing' and the object of each game is to “have as many fish as possible by the end of 10 rounds”. The game teaches system dynamics, ecological principles, responsible citizenship and more!

The Fish Game is often facilitated by Jaimie Cloud in boardrooms, classrooms and auditoriums around the country, and has been played internationally in places like Germany and Kenya.

Users on Apple iOs devices haven’t been able to play the game, and now with Adobe Flash being phased out, The Fish Game Online may not be available to anyone. BUT, you can help. Your donation today of any amount will go towards the development of a brand new Fish Game Online. We appreciate your support

The Fish Game Online has been accessible online for free for more than 15 years, but it needs an UPGRADE.
