Pok�mon Battle Trozei is a sequel to the original Pok�mon Trozei, and as it is a sequel, it comes with numerous changes in the game's mechanics, as well as new features. However, most of these changes are fairly drastic ones that change the way the game is played.

Gameplay Change

The most notable gameplay change is in regards to how you achieve the various combinations in the puzzle. In the original Pok�mon Trozei, you would slide the rows horizontally or the columns vertically in order to match the Pok�mon. In Pok�mon Battle Trozei, however, what you do is pick up a Pok�mon and move it, swapping it with its replacement. This completely changes up the way the game is played.

Like before, you need to make matches of three or more Pok�mon, and when you start making combos, this will reduce to two in order for maximum efficiency. When you've made combos and Trozei Chance/Link Chance activates, you get several seconds to move Pok�mon to continue the combo.
Pok�mon Capture

In the previous game, capturing a Pok�mon was just as simple as matching several of them, and then that's that. However, in Pok�mon Battle Trozei, this is completely changed up. In each level, you will encounter multiple wild Pok�mon that will sit above the playfield. Whenever you make a match and start combinations which count towards an attack against the Pok�mon. These attacks are also factored in by type compatibility so if you start off matching an Electrike, it will be good against a Pidgeot, but not against a Donphan.

Once the Pok�mon's Hit Points are reduced to zero, the Pok�mon is captured and you can move on to the next part of the zone. There are also some occasions where you will face up against more than one Pok�mon at a time.
Pok�mon Attacks

As you are now facing off against specific wild Pok�mon, using the board as means to obtain attacks, the game would be somewhat unbalanced if there was no incentive so you could take your time. This is where the wild Pok�mon comes in. These Pok�mon can occasionally attack you. When they do, your health metre, seen on the side of the table, will reduce. If it gets depleted, the game is over. You can regenerate it by matching up Chansey.

The attacks of the Pok�mon vary depending upon the Pok�mon species, however the power can increase. On the odd occasion, the wild Pok�mon will jump into the table, causing you to have less room to match Pok�mon. When they're at this point, the damage will increase.
