PEAK — Defend Your Own Summit

Seven cards. One summit. Plenty of “that’s PEAK” moments.

PEAK is a colourful, cheeky online card game developed by Innerkid Studios, whose parent company is R3zilient Limited. Match numbers, outplay your rivals and race to empty your hand. Then a Goblin lands, four cards come your way, and your perfect plan suddenly looks… peak.

Your table, your way

• Play solo: challenge three bots on Easy, Medium or Hard.
• Bring friends: create a private room for 2–4 players and share the code.
• Climb together: bot matches and friend matches contribute to one shared leaderboard.
• No signup required: choose a name and jump in. Use your private recovery code to move your scores between devices.

Small cards. Big personality.

• PEAK: lock down the table and take a power turn.
• STAR: counter PEAK during its five-second response window, or try your luck with STAR Hunter.
• Goblin: send the next player a +4 surprise.
• Reverse and Pause: turn the table or stop a rival in their tracks.
• Rare Fairy: choose the active number and earn the freedom to finish on any number.
• Rare Prize: a private power-card surprise for human players. At most one per player per round, and not guaranteed.

Easy to learn. A summit to defend.

Start with seven cards. Play the active number, one above or one below. Normal finishing rules matter: finish on 7 or 8, or a correctly matched 5 or 6. Specials cannot be your final card. Reach 25 cards and you are out. The in-game rules explain every power before you play.

Expect animated card flights, dramatic special-card effects, music, sound effects and a mischievous Goblin snicker. Music and sound have separate mute controls. Reduced-motion support is included.
