User Summary
Shephy is a video game adaptation of the Japanese solitaire card game of the same name.
Starting with a single 1 Sheep, you must build your flock up to the 1,000 Sheep card before you play through the deck of event cards 3 times (represented by a flock of enemy sheep reaching 1000 Sheep before you). On a turn, you choose one card, carry out its effect, then refill your hand to five cards. Event cards might duplicate existing sheep cards, add new ones, swap one value of sheep for another, remove sheep, etc.
The iOS and Android versions are free downloads, letting you play the base game 5 times per day. Buying the upgrade lets you play as many times as you like, and also unlocks the "Challenge" mode and "Post Love" Story mode. On the 3DS version, all modes are available.
