About This Demo

DaiDee 大弟 is a single-player card roguelike built on Hong Kong Big Two combo rules. No opponents, no passing. The puzzle is you versus your own hand and the round’s score target.

HOW IT PLAYS

Each round, draw 16 cards, keep 13, and divide them into legal Big Two combinations: singles, pairs, triples, Straights, Flushes, Full Houses, and Bombs.

You normally have five PLAY resources. Every combination must count, but a non-finishing play containing a natural printed 2 preserves its PLAY resource.

Order matters. Climb Ladders by playing stronger combinations of the same type, or seize the table with a Bomb, to build Flow—the multiplier applied to your Power. Unplayed cards deduct from your final score.

2s are your premium cards. Play a single or group made entirely of 2s immediately after a non-2 combination to create a 2 Link, or end the round with a play containing a 2 to trigger a 2 Finisher. More 2s grant more Flow, while the 2♠ remains the highest single card in the deck.

PROGRESSION AND DIFFICULTY

Between rounds, spend money on Styles that reshape the puzzle. Substitute one card’s rank, turn four consecutive cards into a four-card Straight, chain a Pair into a Straight for bonus Flow, or build around scoring, sequencing, manipulation, and economy effects.

Bosses distort your strategy with special constraints: reversed Ladders, a seat reserved for your highest card, or a Suit Inspector that suppresses native Ladder Flow from matching combinations. Miss the score target and the run ends.
