🎮 the roster

Ten games. One rival.

Short answer
Duelo bundles ten brain games — five word games, two co-op puzzles, a board game and two panic games — and turns each one into a duel against one specific person. 5of the ten can be played asynchronously with a friend, so they never have to be online at the same time as you. Sudoku and Queens are co-op instead — one board, same side.

Questions about the roster

How many games are there?+

Ten, all included and all available from the start. Nothing is locked behind a purchase and nothing has to be unlocked by playing.

Can every game be played with a friend?+

Yes. All ten support duelling someone you invite. Five of them — the word games — also work asynchronously with that friend, so they don't need to be online at the same time. Sudoku and Queens are a shared co-op board. Four in a Row, Bomb Pass and Trapdoor Panic are live only: their boards exist only because two players alternated, so there's no solo run to leave behind.

Which games are co-operative rather than competitive?+

Sudoku and Queens. Both put two players on one shared board with no turns, so you solve them together. Neither affects your rating, because a shared solve has no losing side.
