Super Nova Smash! is a fast-paced phone + card party game for 2-8 players about racing through the blast of a supernova. The goal is to get rid of your cards before your friends — and do as much damage as you can while you go. The deck consists of 96 cards, numbered 0-5. You can play one card higher or lower than the card on top of a play pile, including your on your own pile, and those numbers wrap, so you can play a 5 on a 0 and vice versa. The "0" card is special, though, in that it counts as damage (negative points), counted at the end of the round, so it's best to try to play them on other people's piles while defensively keeping your pile as far from 0 as you can. The app is there to tell you when to play, give you random challenges, and generally make your life a panic-inducing nightmare (in a fun way!). The app will randomly (but evenly) assign turn order and occasionally force all players to compete in quick, frantic mini-games on the device — often when they least expect it. The first person to get rid of all their cards and tap the button in the middle of their screen gets the most Space Points, with fewer points being given to each player as they finish. Once all players are done, they are asked to count their damage (cards marked "0"), and then the app will calculate their scores for the round. Rounds typically last about 3-6 minutes, and the player with the most Space Points at the end of 10 rounds wins! —description from the designer
