Rating & Analysis

Challenge Deck is a category encompassing 20 challenge-mode runs. Each challenge has its own constraints (Joker bans, hand restrictions, $0 starts) and presets specific Vouchers / Jokers.

Notable challenges:

The Omelette: Start with 5 Eggs (value rises per round). Economy-focused play.
Rich Get Richer: Hand levels drop when below $5 — economic pressure.
The Knife: Only 1 hand per round. Demands high-impact hands like Four of a Kind.
Medusa: All cards Stone. Standard hand scoring is broken.
Luxury: High-cost items only. Money management critical.
Cruelty: Bosses have extra effects. High difficulty.

Wins here are about solving constraint puzzles, not the usual scaling-driven runs. Approaches differ wildly from standard play.

Notable Challenge Ratings (excerpt)

Challenge	Difficulty	Comment
The Omelette	C	Egg-economy training.
Rich Get Richer	C	Economy-management exam.

Good Joker Synergies

Each challenge presets specific Jokers, so picks are narrower than usual. Generally strong picks:

Joker	Why
Blueprint / Brainstorm	Versatile even with limited Joker pools.
Bull / Bootstraps	Shine in economy-pressure challenges.
Yorick / The Family	High-burst single-hand challenges.
Fortune Teller / Constellation	Scale based on consumable supply.

Recommended Builds

Approach varies by challenge. Common patterns:

Build	Core Loop	Applies to
Single-hand burst	Four of a Kind / Straight Flush focus	The Knife
Economy pressure	Bull / Bootstraps for damage + cash	Rich Get Richer / Luxury
Egg appreciation	Time Egg sales for max value	The Omelette
Stone-card adapt	Stone-independent Joker scaling	Medusa

Tips & Usage

Read each challenge's rules first — no shortcut around the constraint.
Maximize preset Jokers — that's your foundation.
Standard "good builds" often fail; adapt on the fly.
Clearing each challenge unlocks rewards / next challenges.

Caveats

Magic-Deck-style scaling rarely works.
Challenges unlock sequentially — getting stuck blocks progress.
No Stake adjustments; difficulty is fixed per challenge.
This is a clear-the-puzzle mode, not a high-score chase.
