How a match works

Challenge

Invite a friend through Game Center. No separate account, no sign-up, no friend codes. They do not need to own the pack either: your copy covers the match.

Trade turns

You play a round, they play the same one. Turn-based, so nobody has to be online at the same time.

Highest total wins

Blitz is one round of 5, Quick two rounds of 5, Classic three rounds of 10. Every point counts, and in Quick and Classic one bad round can still be saved.

Made for rivalries

Your move, on your Home Screen

The Active Games widget shows every running match at a glance. You in lime, your opponent in red.

No chat, no noise

There is no messaging in Corto. The score does the talking, which also keeps the game safe for all ages.

No backing out

Leaving a round submits it. Answered questions keep their points, unanswered ones score zero. Choose your moment.

Every match at a glance

The Challenges screen: won-lost-tied record, head-to-head stats, and active matches

The Challenges screen tracks your record, your head-to-head history against every opponent, and every running match. Green bar filling up: that's you. Red counter at zero: that's them, still stalling.

Start as many matches as you have rivals. Each one waits patiently for the next move.

Three generations, one match

Turn-based means a match can span a week and three time zones. A granddaughter in Amsterdam trades rounds with her grandfather in Groningen, one round over morning coffee at a time.

Knowledge beats reflexes in Corto, so it is a fair fight. Knowing where Samarkand is counts for more than fast thumbs.
