On the first week of July you will receive by email your username and password for the game.

To access the “Electrochemistry Game Challenge” platform, you should go to: (you will be able to start playing only from 00:01 CET August 1st)

Once you enter the platform, you can go to “Player details” section by clicking on your name in the upper left part of the platform. There you will be able to manage your avatar including changing your password or your name (this name is the one that will be shown to the rest of the participants). The username to access the platform can not be modified.


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 on 4 questions. Each question has 4 possible answers, being only one of them the right 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.

During the challenge, right answers are labelled with a green tick and wrong answers are labelled with a red cross. At the end of the challenge, you can see a summary.

Once you click on the “Play a Challenge” button in the main menu 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. You can use the drop-down menu to look for the players that are online at the time.

The maximum number of times per day that a player can play agaisnt the same opponent is 2.


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

In case your challenges are not played or you do not play the challenges that other players have sent to you, every day at 4:00 am CET, the non-answered Challenges created 2 days before will be cancelled.

For example, for a challenge started at 11:00 pm CET, on August 1st, if it is not answered by the opponent before 4:00 am CET, on August 3rd the challenge is cancelled. If a challenge is cancelled, the player who started it will receive 3 points but only if he/she answers right at least 3 questions. The opponent will receive no points.

You can find a summary of the challenges you have sent by clicking on “Sent Challenges”, the challenges you have received by clicking on “Challenges to Play” and the challenges you have played by clicking on "Played Challenges”. All these options are in the right side of the platform.


The ranking of the Electrochemistry Game Challenge can be checked in real time in the “Ranking” button.

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:
