In order to support its first public financing campaign, Fondation Tel-jeunes launched Sudoku Jamais seuls, an online Sudoku game.
The game’s goal is the same as the traditional Sudoku, except that it requires two players to play. No artificial intelligence. It can never be played alone.

Completing the grid with someone else makes it cooperative and competitive at the same time. The game is the first of its kind in the world.
First off, the participants are given a hundred tokens, the equivalent of 10 free games. Once all the tokens are spent, the participants are invited to make a donation to the Fondation to get some more.

The gaming experience is enhanced by trophies the players can obtain and by a leaderboard they can climb up when they win. The players can get more tokens by sharing their experience with friends, once these same friends subscribe, but also when they make a donation.
