Gauntlet
Nine cards are your clock. Every opponent is a single round; how deep can you go before the cards run out?
Play →Why is it hard when everything is visible?
Nobody hides a card. You see their hand, they see yours. The only question left is order and timing — which round you give away to win the ones that matter. That makes every position exactly solvable, which is why the app can show you the true optimal line afterwards.
One puzzle a day
Same board for everyone. Count your tries. Share your grid.
