The mechanics of it are purely mathematical, with the aim of the game to create the most multiples of the "Core Number" by mathematically combining the number values of the 16 coins in play. To win the player must meet a predetermined quota of coins used while staying within a set number of turns to use them in.
The game takes place on a 4x4 board with a Core Sphere in the center. The number shown on it is called the Core Number and ranges from 1 to 9. The four fields around the Core Sphere are reserved for the Entry Coins. The Border Coins are the twelve outer fields.
Each coin is numbered from 1 to 9, the objective is to combine these numbers in order to achieve multiples of the Core Number.
During the game the following details will appear at the top of the screen:
At the start of each round one of the four Entry Coins must be selected first, the player is then free to select another coin from either the Entry or Border Coin fields. If the combined sum of these two coins matches one of the Break Multiples, this is called a Core Break which ends the round. If not then the player may continue selecting coins until their combined sum equals one of the Break Multiples displayed.
To win the player must have used up a set Quota of Border Coins within a set number of rounds. If the player reaches the Quota before reaching the maximum number of rounds, the player wins. If they do not reach the Quota, or if they run out of time, the player loses. In the case of a defeat, the player will lose their Entry Coins to the opponent.
There are 64 coins available to play, each with a unique illustration etched on its surface portraying a Fiend or character from Final Fantasy X or Final Fantasy X-2. Each coin possesses a value (1-9) that is used to determine its role in multiplication pairs while some also possess atributes to aid in meeting the game quota or to obtain items or additional coins from the opponant should the player win.
The four placements surrounding the Core Sphere are for the Entry Coins. Chosen and placed by the player these coins will be taken by the opponant should the player lose. Coloured gold these coins are used in combination with the Border Coins to form multiples of the Core Sphere number.
The Border Coins are randomly chosen and placed along the outside border of twelve placement points. Coloured blue these coins are used in addition with the Entry Coins to form multiples of the Core Sphere number. Unlike the Entry Coins, Border Coins disappear after being used while the remaining Border Coins' values are increased by one (any coins with values exceeding 9 will also be disgarded or replaced after this increase).
Echo traits allow the player to obtain bonus Quota points. However to initiate an Echo the player must not only select an Entry Coin with the trait but also maintain a set play pattern.

|Quota x4||If this Coin is selected first, the Quota will be multiplied by four depending on the amount of Border Coins used to make a Core Break|
|Quota x5||If this Coin is selected first, the Quota will be multiplied by five depending on the amount of Border Coins used to make a Core Break|
|Rare Coin||A Border Coin with the Rare Coin trait will appear|
