The goal of the game is to get as much points as possible.

The first 10 players with the highest amount of points will receive a prize, described in section “5. Prizes”.


The Game is based in challenges between 2 players.

Each Challenge consists of 4 questions. Each question has 4 possible answers, being only one of them the correct one. There is a limited time of 60 seconds for answering each question; if the question is not answered before that time, it is considered a wrong answer.

When playing a challenge, both players receive the same questions and the challenge is played in turns: first the player who challenges and then the player who receives the challenge. Therefore, it is not needed that both players are connected at the same time.

At the end of the challenge, you can see a summary of your answers.

To play a challenge you need to click on the “Challenge a player” button in the upper part of the platform, and you will find 3 types of challenges:

- “Challenge a player” button: You can play a challenge against a player of your choice. To look for a player you can write his/her name in the “select a player” field or you can use the drop-down menu to look for the player.

- “Random challenge” button: You can play a challenge against a player randomly selected by the platform.

- “Online challenge” button: You can play a challenge against players who are currently online. To look for a player you can write his/her name in the "select a player" field or you can use the drop-down menu to look for the player.


Once both players have played the challenge, the player who has answered correctly more questions receives 4 points; the other one receives no points. In case both players answer correctly the same number of questions, the winner is the one who answers them faster.

In case your challenges are not played by your opponent or you do not play the challenges that other players have sent to you, they will be suspended 3 days after the day they were launched. If a challenge is suspended, the player who launched it will receive 3 points but only if he/she answered correctly at least 3 questions; the opponent will receive no points.

In the left side of the platform you can find the finished challenges that you have played by clicking on "Played challenges", the challenges you have pending to play by clicking on "Pending challenges", and the total number of active challenges pending to play by you or by your opponent by clicking on "Active challenges".
From "Active challenges" you can enter to play the challenges by clicking on the arrow found in the right side of the platform.


By clicking on "Ranking" in the upper part of the platform or on "Personal ranking" in the left side of the platform you can check your position in the game and the ranking of the first 20 players.

On Thursday August 8th at 14:00 CET the competition will be closed, and no more challenges will be available to play.

At that moment, the player that has more points will win the first prize, followed in order by the next players until 10. The available prizes are:
