// Geometric Pressure.

We stripped away the RNG. What remains is a pure system of kinetic energy and structural integrity.

[01] 01. Formation

Your 4x2 grid is your survival. A gap in the front rank is an invitation to destruction. Every card is a tactical data-point.

[02] 02. The Cascade

Damage flows front-to-back. Suits like Diamonds and Clubs modify the kinetic energy as it breaches each rank.

[03] 03. Determinism

Identical inputs. Identical outcomes. Your victory is not a roll of the dice; it is mathematical inevitability.

The Death of Luck

In Phalanx Duel, there are no coin flips. Identical inputs produce identical outcomes. Every combat result is hashable, verifiable, and mathematically inevitable. Your victory is yours alone.
