Knowledge is Power: Decades (EP)

Go to the game settings. Select Quick game. We turn off the techniques. We connect 2 devices. We create and confirm characters. Let's start the game. We block one device and play on the other. To speed things up, select any answers and any epochs. The main thing is to finish quickly and get the scroll. One quick game takes approximately 6 minutes.

30 games * 6 minutes = 180 minutes = 3 hours. The fastest option. The remaining modes take a long time to play. Sometimes you come across a sorting test and in this test you can reduce the time to 5 minutes. Quickly move the answers in any direction and you will pass the test in a couple of seconds. You won't have to wait 1 minute for the test to end.

By time:
Standard game: Longest. About 30 minutes.
Quick game: 5 - 6 minutes. Depends on the last test. ***
Quizzes (Tests): From 13 minutes. If you know all the answers, it will be faster. ***
Questions only: 6:30 minutes minimum.

*** But! There is a trick with Tests and Questions. Game setup - Quizzes. Next are 2 devices. As soon as you start the game, immediately block one phone and the second. The test will immediately end as soon as the game realizes that none of the players are there. As soon as the game starts counting points, connect any device to click on CONTINUE. That's all. All you need to do is disconnect the phone and connect it using the CONTINUE button. The tests will be reset and it will be faster this way.
I would recommend a quick game. I think this is the fastest. The introductory cutscene lasts 1 minute.
