Two-player, fast paced card game. Strategically move cards around and predict the final outcome.
Setup
The middle playing field is the river. It has 5 slots, indicated by 5 face-down cards. These cards are there to indicate the river's slots and their values never come into play.
The playing field in front of you is your hand. You start with an empty hand.
Your turn
You may hold at most 5 cards in your hand. On your turn, do one of:
Draw the top deck card to your hand. Disabled when your hand is full.
Play a card from your hand:
Number (1, 2, or 3 — stones, fish, reeds): place it on top of any river slot. Each slot holds at most 3 cards including the initial face-down.
Predict (1, 2, or 3 — stone, fish, or reed): place face-down next to a slot on your side. Hidden until game end. Each player can place one prediction per slot.
Swap: swap the entire stacks of two river slots. The swap card is then removed from play.
Remove: remove the top card of any river slot (you can't remove the face-down initial). The remove card is then discarded.
You can drag cards onto a target as a shortcut, or click a card and then click the destination.
Card backs
Card backs hint at type without revealing the value:
Blue back = number card (so the deck top tells you the next draw is harmless).
Brown-red back = action card (prediction, swap, or remove).
The end
The game ends when any of: the deck runs out, every river slot has 3 cards, or the next player has no legal action. All face-down predictions flip face-up.
Scoring
For each prediction you placed, compare it to the top card of its slot:
Exact match → double payout (predict stone → +2, predict fish → +4, predict reed → +6).
Top card is higher than your prediction → partial credit, +1.
Top card is lower, or the top is still face-down → penalty, −1.
Highest total wins.
Tips
Prediction values are hidden — opponents see that you predicted, not on what. Use that to bluff.
Predicting reed (3) pays the most on a match but punishes you for any miss.
Predictions placed early can drift up — even predicting stone (1) with a top of 2 or 3 still scores +1.
Swap cards are your main offensive tool — use them to wreck opponents' predictions.
Cards left in your hand at game end are worthless — play them.
