Fushimi Roku casually picked up a metal card and closely examined its appearance. It was engraved with only the number "25," with no other patterns or decorations.
Before the arbitrator announced the official start of the gambling game, he seized every second to start thinking.

The water level was still rising rapidly. Fushimi Roku glanced sideways outside the glass chamber and quickly retracted his gaze. Naturally, in a life-or-death gambling game like this, he could not rely on others.
Since "deducing the conditions for victory or defeat is also a part of the game," it indicates that the "conditions for victory or defeat" can be deduced. By gathering enough elements for deduction, one can reasonably speculate the card playing rules.
