There's not much to Exploding Kittens. Each player starts with a hand of 5 cards plus a Defuse card. In your turn, you play cards from your hand, then draw a card at the end of your turn. Some cards are just pictures; play a matching pair and you can steal a random card from another player. Some cards are Favours - they force another player to give you a card of their choice. Some cards are Skip cards that let you immediately end your turn without drawing a card, some are Attacks which do the same then force the next player to take two turns in a row. Nope cards cancel out a card played by someone else (or can cancel their Noping of your card, and so on).
Why would you want to avoid drawing a card? Because if you draw an Exploding Kitten, you explode and you're out, unless you play your Defuse card. If you do, the Kitten goes back in the deck anywhere you choose (so, if you know the next person doesn't have a Defuse card, put it right back on top!
Last unexploded player wins.
Oh, and when you open the box, it goes "miaow".
