Grab a friend. You came to kill five minutes; you'll stay the whole afternoon. The board game you both play at the very same instant—nobody waits… anything can happen!
You both move at the same time, in secret. Only when the turtles land do you find out whose plan just fell apart.
Oh no — this ain't your traditional five-in-a-row. What the Shell is the one you reach for when you and a friend are bored on the couch: "Wanna play What the Shell?" A game between two beginners can be over in three minutes, and somehow you're still at it two hours later, laughing every time your minds collide and another egg turns up on the board.
"Simultaneous play boosts the fun of this intuitive, yet surprisingly deep board game."
— Matthias Titze, Clarc producer (German Computer Game Award winner)
There's no taking turns, and nobody goes first — so nobody gets the first-player edge. You lock in your move, your friend locks in theirs, and the board resolves both at once. Strategy still wins games, but you're up against a mind you can't see, and you never know where she just played.
Sandwich two of their turtles and they're gone. Both reach for the same square and your turtles crash into an egg — and an egg is a curious thing: you can capture it, or hatch it. One bold move flips a game you'd already written off. Capture at the right moment and a chain reaction can tear through the position your friend spent the whole game building. It's never won or lost until the last move.
Made for two:
• Sit down together, each on your own phone or tablet, and battle it out face to face — best enjoyed in the same room
• Or play online at your own pace, whether your friend's across town or across the world
• No one around? Tap Quick Match for a random opponent, or take on the panda offline, from an easygoing Newcomer to a tough Expert
• Got a controller? Connect it to your iPad or iPhone and play however you want
Read the board, then read your friend. Capture a couple of turtles, deal with the eggs, line up five in a row — and enjoy the look on his face when it all comes together.
I don’t play mobile games as often as I used to, and when I do, I don’t typically play games like this. But boy is this one addicting when I get into it. There’s a little learning curve as you understand the ways of playing well, but you quickly build skill. It’s fun with a bot, and good lord do I have a hard time putting it down if I’m playing it with a friend.
