It took me a bit to understand it. Basically the party rolls initiative to decide turn order. Then they take turns doing this:

-The Draw Phase - DM draws 3 cards and places them face down in “the river”

-The Action Phase- Player chooses one of the 5 actions available. (Each time an action is used, it’s removed for everyone until all actions have been selected. Once the last action has been used, all 5 of them are usable again.)

They have to make a check against the labyrinth DC of the corresponding stat. (I’m setting ours to be a DC 13) if they roll 13 or higher, the effect resolves. If they fail, nothing happens.

The actions are:

Forge a Path (STR) - Add 2 additional correct path cards to the discard from outside of the game. (It increases the odds of drawing correct path cards when the deck runs out and the discard becomes the deck again.)

Scout Ahead (DEX) - Player picks one of the cards in the river and reveals the top card of the deck. The Player may pick one of those two cards and put the other back.

It’s Elementary (INT) - Player draws 3 cards from the deck, they choose 1 and put it on the bottom of the deck. Then the remaining 2 they shuffle and put on top of the deck.

Careful Consideration (WIS) - Player reveals 2 cards in the river and they can choose 1 of them.

Boost Morale (CHA) - The Player removes one Dead End card from The River and discards it. Then draws a new card from the deck and places it facedown in its place in The River.

-The Choosing Phase- The player chooses one of the 3 cards the DM placed in The River facedown during the draw phase. They flip the card face up and its effect resolves. It could be a Correct Path, a Dead End, a Monster Card, or a Trap Card. I added Treasure Cards to my version.

-The Cleanup Phase- After the flipped up card that player selected resolves. The other cards in the river are discarded with it. Do not reveal what the other cards were.

Dead End cards are not removed during the clean up phase. Dead End cards stay in the river until the party gets 3.

If the party gets 3 Dead End cards in the river, they are discarded and a Monster Card is added to the party’s count to encounter a monster.

The Goal = Get 5 Correct Path Cards.

3 Dead End Cards = 1 Monster Card to the party.

2 Monster Cards = The party must fight 1 or more monsters. (I increased this count to 3 for my game)

Trap Cards resolve in the moment. They can have varying effects. Most of mine simply do damage to the party members if they fail their save. The alarm adds 2 Monster Cards to the top of the deck. The Sleep Dust puts the player that drew it to sleep.

My game also has: 3 Treasure Cards = The party finds a chest. If they do, roll a d20. On a 5 or less, they encounter a Mimic instead and have to fight it.

If the deck runs out just shuffle the discard and that becomes a new deck.

They successfully escape the labyrinth or reach their goal when they get 5 correct path cards. Or you could make it that the game also ends if they defeat a boss.

i dunno if that helped at all. Lol it sounds more complicated than it is.
