I want to introduce you to the
team test from the Swedish Armed Forces, a team flash game. The essence of the game, it would seem, is simple, you need to perform various tasks for memory and concentration.

For a correctly completed task, time is added, for an incorrectly executed task, it is subtracted. Many of these games are on the Internet, what is the highlight you ask, but in what: for the successful execution of the task, time is given not to you, but to your teammate. Also, your time is entirely dependent on your partners. These are the simple rules here, but the game is very exciting and unusual, lets you feel the beauty of teamwork.

You can also create a private link and give it to friends to play together, and not with random partners. It looks like this:
team.forsvarsmakten.se/english/#/private/habrThe game is played by a team of
exactly four people, so that the whole habr on this link does not fit, sorry :)
