Final Fantasy X-2/Sphere Break

Game board: Core Sphere (light blue) surrounded by center coins (gold) which are in turn surrounded by border coins (dark blue)

The Sphere Break minigame is a bit like Sudoku, as the game has a numerical grid that has to be dealt with using a set of rules. The mechanics of the minigame are purely mathematical, relying on sums and multiplications; the aim is to create the most multiples of a "core number" by combining numbers of the 16 coins on the board.

Coins

Coins.

Coins are numbered from 1–9 and possess several different attributes that can help you in the main game or in the Sphere Break minigame itself (free magic item, free potions, echo, more coins, quota multipliers, etc.).

Entry coins

You will be playing against the dealer (owner of the Core Sphere), and must select four coins to bet. They will be your entry coins and will be placed in the center. During the game, every time the dealer rolls a number on the Core Sphere, you have to pick at least one entry coin to start your turn.

Border coins

At each turn, 0–12 coins surround the center coins and the Core Sphere. You use them to make a Core Break. At each turn, any coin not used in a Core Break is increased in value by one. If it had a value of 9 before, it is removed from play as they cannot be a value of 10. Coins used in a Core Break are also removed. Empty spaces are filled (or not) randomly, with a new coin valued from 1–9.

Core Break

A Core Break happens when you select coins that, added to each other, form a sum that is a multiple of the number rolled by the Core Sphere. You have to obtain a Core Break in a set limit of time or you lose the game. A Core Break ends a turn in the game.

Game mechanics

1. Like a dice, the dealer makes his Core Sphere produce a number from 1–9 for a set number of turns, i.e. 20 turns.
2. For each turn, you have to use at least one of your center coins, which, on the tournament of Final Fantasy X-2, are preset 1, 2, 3 and 5 with multiplier echo.
3. Each turn has a set time limit from (60 seconds, 30 seconds, etc.) and you have to produce a multiple of the Core Sphere within it. If you fail, you lose the game and also lose the center coins you bet.
4. Each game has a "quota", i.e. a set number of coins that needs to be used in the games set umber of turns. If all turns are used and you did not complete your quota, you lose the game and also lose the center coins you bet.

By using the multipliers and other coin attributes, you can beat dealers with very difficult Core Spheres. The current champion Shinra has a quota of 100 coins that have to be obtained in just 15 turns with a time limit per turn of 45 seconds.

A sample game

A very easy game with low quota, lots of turns and large time limit per turn.

• Quota: 30 coins
• Turns: 20 turns
• Time limit per turn: 60 seconds

Turn 1

For the first turn, the dealer rolls out a number from 1–9, i.e. 7.

In your first turn, you need to find a multiple of 7 by adding the center coins (1, 2, 3, and 5 with multiplier echo) and the 0–12 border coins (randomly set). Here you could just use center coins (2+5), but this is not to your advantage because center coins do not add any coins to the quota of 30 coins you have to use before your 20 turns are complete. You have to pick one center coin, for instance 2, bringing the sum to 2.

Now you look at the border coins and try to get as many border coins as you can to make a multiple of the Core Sphere's 7. Since you already picked a 2 the maximum sum of the border coins you can pick has to be either 5, 12, 19, etc. to yield a multiple of 7, such as 7, 14, 21, etc.

If you pick three border coins: 8, 8 and 3, making your total sum 21 (2+8+8+3), you'll obtain a successful turn, i.e. a Sphere Break. Your quota is now equal to three coins and your multiplier is 3, because you closed the turn with 21 which is 3×7. The multiplier is important, because one of your center coins has the multiplier echo attribute and will help augment your quota in the next turn.

Turn 2

On the second turn, the Core Sphere rolls a 1, which is good for the dealer and bad for you.

Faced with a 1 from the Core Sphere, you are forced to pick only center coins, as any number you pick will be a multiple of 1 and you have to start by picking a center coin. This means you will not get any extra coins to add to your quota this turn.

As noted above, any center coin (1 ,2, 3 or 5) will end the turn. To be clever, you would use the multiplier echo to your advantage here and pick the 3 center coin. This will make your multiplier for his second turn to be equal 3, which is what 3×1 amounts to. Note that the turn ends with the same multiplier as the last turn: 3. This means you have a multiplier echo.

The turn ends with a quota of 3 (no border coins were added) and a multiplier echo of 1.

Turn 3

For the third turn, the Core Sphere rolls a 2.

You want to pick your mandatory center coin to be odd, because any coin that is even will end your turn. For instance, you might pick 1.

For the border coins, you can now keep on picking odd coins, but to take advantage of the multiplier echo, you need to stop when your sum totals 6, which is 3×2 and gives you another multiplier echo. You might pick a 5 border coin, making your sum equal 6 (1+5) and making another multiplier echo.

The turn ends with a quota of 4 plus the echo bonus of 2 multiplied by your quota on this turn, which is 2×1, giving you a total quota of 6 and a new multiplier echo of 2.

Turns 4–20

The game proceeds until either all 20 turns are completed or the quota of 30 coins is fulfilled. If you fulfill your quota before the end of 20 turns, you win the game and all the prizes yielded by the border coin attributes.
