Diving Suits is a card game for 2-4 people (maybe more, but then you'd probably want to add more decks). Players are divers on a race to reach the bottom of the ocean.

Ingredients: a standard 52-card deck

Setup: - shuffle the deck - each player draws 4 cards - open 4 cards from the deck on the table - open one more card as the start of the discard pile - set each player's current depth as 0 and current oxygen level as 10 (using paper, dice, whatever; bear in mind that depth goes from 0 to 100 and oxygen goes from 0 to 10)

On each turn, a player can play a card either from their hand or from the table. If it was played from their hand, they draw another one. If it was played from the table, open another card to replace it.

These are the effects that will happen depending on the card you played: - Ace (=1), 2, 3..., 10 ("number cards"): - Place it on the discard pile, then you go down by that many points (i.e. add the card value to your depth) - If the card matched the rank and/or the suit on the top of the discard pile, it's value is doubled - Then you spend your oxygen depending on their current depth: - between 0-25: 1 oxygen level - between 26-50: 2 oxygen levels - between 51-75: 3 oxygen levels - between 76-100: 4 oxygen levels - J ("Jolt") - Place this card in front of any player lower than you (i.e. with more depth than you) - Next time that player plays a number card, they will go up instead of down (because you pushed their cable); they put both their played card and the J on the discard pile, in any order they choose - Q ("Quick") - Place this card in front of you - Next time you play a number card, you will go down by an extra 8 points, but you must pick another player to go down by 4 points; both players spend their respective oxygen levels; this Q card is then placed on the discard pile (over the number card). - K ("Knot") - Place this card in front of another player - Any time that player would try to recover their oxygen levels (see below), they won't recover any (you tied a knot on the cable that brings them oxygen); they put both the card(s) they chose to discard and the K on the top of the discard pile in any order

Recovering oxygen: instead of playing a card for its effect, you can discard one or more cards from your hand and draw that many again. Depending on how many cards of the same suit were discarded you get some oxygen levels (you can't have more than 10 of it): - no repeated suits: 1 oxygen level - two cards with the same suit: 2 oxygen levels - two pairs of cards (e.g. two hearts and two spades): 3 oxygen levels - three cards with the same suit: 4 oxygen levels - four cards with the same suit: restore oxygen levels to 10

Extra rules: - a player with 0 oxygen levels will be rescued back to depth 0, where they get back 10 oxygen levels - each player can't have multiple cards of the same rank placed in front of them (so, no stacking 4 Qs in front of you, nice try though) - if a player has both J and Q in front of them, Q won't "trigger" until they get rid of J first (no going up and down at the same time, let's keep the game paradox-free) - if the deck runs out of cards, just shuffle all but one of the discarded cards back into it

Whoever reach depth 100 first wins the race!

PS: most of this were ideas I had during the Jam weekend, but I had to travel to another state at that time so I couldn't make my usual NES entry. But because FOMO is a thing - and I was already regretting that I missed the first D2JAM - I've decided to at least submit my idea as a very much untested physical game on the Extra category before LD ends.

PS2: feel free to re-scale the points for flavor purposes (e.g. use "100m" as a depth unit instead of "1 depth")
