Tower calibration minigame (Rikku).
The tower re-calibration minigame can be played in Chapter 2 and 3 in the Thunder Plains in Final Fantasy X-2. To start, the player must talk to the Al Bhed Technician by the first tower twice. The player receives prizes in Chapter 5 depending on how many times they calibrated a tower (maximum is 30). Finishing this minigame gives no story completion %, nor is playing it required for an Episode Complete.
The player has to enter a series of 30 randomly generated commands. The player has three chances per calibration to complete the tower, and if they miss more than three they will have to re-calibrate the tower from the beginning. The number of misses affects nothing as far as prizes are concerned. Once the player has successfully calibrated the whole tower the player can redo it, but if the player already finished all 30 sequences once, there is no need to do it again. The number of failed calibrations does not affect the player's calibration or prizes.
There are ten towers on the Thunder Plains. The first towers are easier and then it gets gradually harder.
How to play[]
Rikku[]
Rikku plays the "Appear and Disappear Calibration" where buttons briefly appear on the screen and the player must press the combination to complete the sequence. If the player isn't fast enough they will miss. Rikku's towers are Towers #1, #4 and #7. In the first tower the button sequence appears in the middle of the player's screen, but in the others they appear in random locations around the player's field of vision. In the first tower the only buttons are the 
, 
, 
and 
, but Tower #4 adds 
and Tower #7 adds 
and 
and the player must press two buttons simultaneously. The button sequences start slow but get faster toward the end. For Tower #7, after the 25th sequence, the commands appear onscreen for only 1.5 seconds.
Paine[]
Tower calibration minigame (Paine).
Paine plays the "Avalanche Calibration" where the commands fall down in three rows from top to bottom. There is a halfway mark where a command will flash and the player must press the button that flashed before the rows fall to the bottom. If the commands hit the bottom, or the player pressed the wrong button, it will be a miss. The speed will increase further into the calibration. Paine's towers are #2, #5 and #8. Tower #2 uses the , , and and , and Tower #5 and #8 add and 
.
Yuna[]
Tower calibration minigame (Yuna).
Yuna plays the "Forgotten Memories Calibration" where the player must remember the button sequences shown onscreen consisting of two phases: a Memory Phase, and an Input Phase. In the Memory Phase the commands appear once before disappearing while the new command appears. The player must remember the commands listed in the sequence. The speed and number of commands will increase. In the Input phase, the player has to input the commands that appeared in the Memory Phase. There is a time limit. If the player inputs the wrong command, or takes too long, it will be a miss. Yuna's towers are #3, #6, #9 and #10. For Towers #3 and #6 the number of commands in Memory Phase starts at two and increases into three and then four for the latter stages of calibration.
For Tower #9 the number increases to five in the latter stages, and Tower #10 to six. Tower #3 uses the , , and buttons, Tower #6 adds , Tower #9 adds and and Tower #10 adds 
and .
Tips[]
The player can place their fingers on the buttons as they appear in the Memory Phase to better remember them for the Input Phase. Tower #10 is different because it is played in reverse. The easiest way to complete this tower is to use someone else to assist in memory and write down the commands that appear. The player can also write down the commands themselves if they're quick enough to pick the controller back up, or can hold the controller in one hand while using the other hand to write the commands down. Another way is to repeat the sequences out loud as they appear to help remember them better.
If playing on PC, the player can use the built-in feature to hit the Esc button on the keyboard for a "master menu" at any time to pause the game, even at places where the developers disabled the regular pausing with the pause button to prevent players from "cheating" the timed challenges.
Prizes[]
The player receives the Samurai's Honor Garment Grid for completing all the towers. At least five of them must be calibrated to completion, or 30 successful inputs. Misses do not affect anything.
For the individual towers the player can find a prize in a treasure chest that appears after defeating a fiend at each tower in Chapter 5. Each prize varies on the tower and the number of times they calibrated it.
