🎮 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. Eight of the ten can be played asynchronously, so your opponent never has to be online at the same time as you.

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. Eight also work asynchronously, so your opponent doesn't need to be online at the same time; the two panic games are live-only because a game of nerve doesn't survive an eighteen-hour gap.

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.
