Choose your opponent

Invite a player by name or code, or choose Play the computer in the lobby. Start with Analyst Edge, challenge House Edge, or take on Counter Edge. These three follow the same rules and cannot see your hidden cards. Their results count in your overall and head-to-head records.

Wildcard Edge: House Rules exhibition. This fourth opponent can cheat, peek, swap cards, and offer deals. Results never affect statistics or history. One row is low-hand-wins, announced before play. Every trick waits for your response: allow it, use Play Fair!, call a suspicious bluff, or accept/decline a deal. Open Tricks for your redraw and row-swap powers, the trick log, and the full rulebook. Fresh deal restarts whenever you like; the current board saves so you can resume.

1

Five hands: 4 shown, 1 hidden

You build four rows your opponent can see, plus a concealed hand only you can see. Those five poker hands are what get scored.
A hand: two pair, aces & nines
2

Start with five hidden cards

Each player is dealt a concealed hand of 5 cards to begin. Your opponent can’t see them.
3

Draw one, place one

On your turn you draw a card (now holding six). Then place one card — the drawn card or a held one — into one of your four rows. Drag a card from your hand onto a highlighted row, or tap a card and then tap the row. You always keep five cards concealed.
4

One discard per game

Once per game, instead of placing, you may discard a card you don’t want — great for ditching a card that would spoil a hand.
5

Your concealed hand is your 5th hand

When both players have filled all four rows, everything is revealed. Your held 5 cards become your fifth hand. Each hand is compared to your opponent’s in the same spot — win 3 of 5 to win the game, all five for a Five-O.
6

First to 5 wins the match

Keep playing games — the first player to 5 game wins takes the match, and it all feeds your lifetime stats.
