First round

The four contestants have to put back words (proper noun, common noun, adjective or verb) in the correct order as fast as possible. They win points based on the speed with which they answer. Two cross-referenced themes are presented by the host. The series is made up of five words to find. For the first four words: At the host's request, the first word is shown on the set screen. The letters that make up this word are divided within 3, 4, 5 or 6 rings. These movement-animated rings are set in disorder and appear simultaneously onscreen. The word is shown for 20 seconds.

After the first 10 seconds, a clue is given to the four contestants. Each contestant must, within the 20 seconds given to him, give his answer and confirm it. At the end of these 20 seconds, the word disappears from the screen. Each contestant's answer time is recorded and helps to establish their ranking, from the fastest to the slowest. Points are given based on this ranking: 5 points for the fastest, then 3 points for the second contestant, 2 points for the third and finally 1 point for the slowest contestant. If a contestant gives a wrong answer or does not confirm an answer within the 20 seconds, they receive no points.

For the fifth word: the rules are the same as with the first four words. But the points distribution is not: the fastest contestant wins 10 points, 6 points for the second contestant, 4 points for the third and finally 2 points for the slowest contestant. Following these five words, each contestant's console shows the number of points accumulated. The contestant with the fewest points is eliminated and leaves the Game for good. The three remaining contestants are qualified to take part in the second round.

Second round

The contestants’ scores are reset. The challenge given during this round changes from one show to another based on a predetermined order each week:

• Picture challenge: The remaining contestants play with a series of five words shown one after the other. For each word, the letters or groups of letters are separated and appear in a series of 3, 4, 5 or 6 rings. These rings appears simultaneously, are disordered and movement animated. One of the groups of letters is replaced by a picture.
• Intruder challenge: The setup is the same as for the picture challenge. Instead of a picture, an extra ring containing a useless letter or group of letters is shown.
• Empty ring challenge: The setup is the same as for the picture and intruder challenges. Yet this time, one of the rings will be empty of the corresponding letter or group of letters.

For the first four words: A predetermined theme is indicated for each word. At the host's request, the first word is shown on the set screen. The letters and/or images/empty rings that make up this word are divided within 3, 4, 5 or 6 rings. These movement-animated rings are set in disorder and appear simultaneously onscreen. The word is shown for 20 seconds. After the first 10 seconds, a clue is given to the three remaining contestants. Each contestant has on his console a touch screen enabling him to set the rings in the correct order so as to find the word in its correct spelling. Each contestant must confirm his answer. At the end of these 20 seconds, the word disappears from the screen.

Each remaining contestant's answer time is recorded and helps to establish their ranking, from the fastest to the slowest. Points are given based on this ranking: five points for the fastest, then three points for the second contestant and finally one point for the slowest contestant. If a contestant gives a wrong answer or does not confirm an answer within the 20 seconds, he receives no points. For the fifth word: the rules are the same as with the first four words. But the points distribution is not: the fastest contestant wins 10 points, six points for the second contestant and finally two points for the slowest contestant. Following these five words, each contestant's console shows the number of points accumulated since the beginning of the round. The contestant with the fewest points is eliminated and leaves the Game for good. The two remaining contestants are qualified to take part in the semifinal.

Semifinal

Scores are reset. A series of 9 words is prepared. Each word is divided into letters or groups of letters within a group of 4, 5 or 6 movement-animated rings. These rings appear one after the other with a 4 seconds interval between them. The clue appears first and the total onscreen time for each word is 20 seconds. The first of the two contestants that recognizes the word must press on his buzzer to give out loud his answer. If the contestant gives a correct answer within 3 seconds, he gets 1 point and the host asks for the next word. If the contestant gives a wrong answer, he can't buzz anymore. The other contestant can then answer when he wants, within of course the remaining time left before the 20 seconds are up. If he gives a correct answer, he gets 1 point. The first of the two contestants that reached 5 points qualifies for the final and the following show. The other contestant is eliminated and leaves the Game for good.

Final

The finalist is in front of Harry. He has 80 seconds to find 10 words in a list that passes before his eyes. Each word is chopped up in letters or groups of letters set within movement-animated rings. The difficulty of the words progressively increases the more words appear on screen, with an increasing number of rings. Each word is shown onscreen for a maximum of 8 seconds. However, if the contestant finds the word before the time is up, the next word is show. The answer is given out loud by the contestant. For each word found, the contestant goes up a notch on the winnings scale that ranges from €50 to €2000. For each wrong answer or lack of an answer once the 8 seconds are up, the contestant goes down a notch. The contestant wins the sum reached at the end of the 80 seconds. Furthermore, he is automatically selected to take part in the next show. His winnings are cumulative for show to show and are considered his for each show won..
