In Hi Lo Flip, you want to ditch all the cards in your hand, while also keeping others from playing so that you can collect the discard pile for yourself.
Each round in the game, you start with a hand of seven cards from a deck numbered 1-100. The HI-LO chip is in the center of the table showing one side of it.
On a turn, you play a card from your hand onto the discard pile that is either higher or lower (depending on the HI-LO chip) than the current top card. If you can't play, then flip the chip.
If it lands on the opposite side, play a card, then end your turn; if not, then draw a card, playing it immediately, if possible.
If you still can't play, then whoever played most recently claims all of the cards in the discard pile, then you play whatever card you want.
If you play a card that ends with a 1, then the next player draws a card and skips their turn. If the card ends in a 2, then you must play again.
When someone runs out of cards, they collect the discard pile, then players tally their points for cards collected, with cards ending in 0 being worth 10 points and all other cards 1 point.
The player who went out scores a bonus of 10 points. Complete multiple rounds until a player scores more than 75 points, with whoever has the highest score at that point winning the game.
