Usogui's Air Poker Explained

Overview of the Air Poker Game in Usagui

Air Poker is a complex game featured in the manga series Usagui.
The game revolves around Lalo Vincent's plan to regain his eligibility as Kaiser and surpass The Leader.
Players, including Baku and Lalo, are confined to chairs and must avoid losing by staying seated for 10 seconds.
Each player starts with 25 bios of pressurized air for breathing and betting, with each bio providing approximately five minutes of breathable air.
The game is centered around metal cards, each representing a number with hidden significance and hierarchy.
Once a card is used in a poker hand, it cannot be used again in the next rounds, adding dynamism to the card values.
The chosen card number is transmitted to Hal and fukuru on the Upper Floor, where they construct a corresponding poker hand.
Failure to match the sum or using a card already used results in a lost round.
If both Upper Floor players make a mistake, they receive extra time to craft a new hand.
The game on the Lower Floor is a matter of life and death, while the Upper Floor players are protected by the witch pain device, which simulates intense suffering without causing harm.
Hal, the leader of kakaru, needs to stay alive to play surpassing the leader against the winner.

Lalo conserves his air bios by rising and taking a deep breath before the water fills the tank completely.
Baku tampered with Lalo's bios pressure regulator to create the illusion of an empty bios.
Lalo wins the first round with card 15 while Baku chooses card 36.
Kaji highlights the strategic safe zone where a player has more air bios than their opponent.
Baku wagers all his bios in the second round, but Lalo takes his time over his next move.
Fukuru wins the second round with a full house, but Baku couldn't grab the air bios in time and almost drowned.
The air bios now stand at 29 for Baku and 16 for Lalo.
The players fear encountering the harrowing witch pain again after experiencing it.
Baku expends a significant amount of air as he contemplates his strategy in the third round.
Baku unveils the law to Lalo to provoke him into playing his most potent card, number 47.
Lalo hypothesizes that Baku's revelation of the law was a ruse to force him to use his Ace card.
Baku strategizes to weaken Lalo's remaining cards and secure victory in this round.
High card numbers grow more powerful as many poker hands have already been deployed.
An Ace card can lose its potency if the required cards have been previously played.

Lalo and Baku are in the final round of the poker match.
Lalo only wagers two air bios instead of the maximum limit.
Baku realizes that if he loses no more than five air bios, he can secure the match with one more victory.
The Arena's lights go out due to a calamity.
Both Lalo and Baku have used the Ace of Hearts, resulting in Baku losing five of his remaining bios.
Lalo had foreseen this possibility before betting his two bios, effectively negating Baku's advantage.
The BIOS now stand at 19 for Lalo and 17 for Baku.
Baku notices that Hal, the leader of Kakaru, isn't observing the match and contemplates the possibility of Hal influencing the game.
Baku sends a coded Morse message stating "it's 36" to relay information to Hal.
Hal deciphers the intended meaning to be number 25.
Referee Noah Shion unveils the Upper Floor to the audience for the fourth round.
Kaji deduces that Baku must utilize card number 25 to prevent its weakening, while Lalo is compelled to play card number 63 to avoid losing the final round.
Baku chooses card number 26 as an unexpected move.

Baku gains an advantage with two remaining air bios.
Lalo becomes suspicious of Baku's strategy when he notices glass shards from the first round lodged in Baku's air bios.
Lalo realizes that Baku had concealed his remaining air bios, making him believe that folding would have resulted in his defeat.
Baku's strategy, known as the landmine, traps Lalo into matching his bet to the limit.
Lalo ends up with 10 air bios while Baku appears to be out of breath.
