In the Golden Needle challenge, it's possible to get two hands using unbanned vouchers and a glitch with the Needle boss, which doesn't seem intended:
- Start the Golden Needle challenge ("Only 1 hand per round")
- Buy the Hieroglyph voucher. This subtracts one hand, reducing the count to 0.
- Upon selecting a new blind, the hand count resets to 1, which appears to be the intended behaviour.
- Play against the Needle boss ("Play only one hand")
Instead of the Needle forcing the hand count to 1, you end up with 2 hands!
(Guessed cause)
The Needle sets hand count to 1, and then a Hieroglyph-GoldenNeedle edge-case kicks in giving you +1 hand (rather than setting hand count to 1), resulting in 2 hands
