The Controls in Pokemon Trozei are extremely simple.  Slide Pokemon up,

down, left or right to create groups of four or more (Trozei).  You can slide

Pokemon off any edge of the screen but the top and they will loop around to

the opposite edge.  This helps you move Pokemon around.  Trozeied Pokemon will

then disappear, and trigger a continuous Trozei.

During a continuous Trozei, you have the ability to create matches with

three or more Pokemon.  When you match three you are able to create trozeis

with only two.  This continues until you stop making matches or you clear

the screen.

Random Pokemon will fall in every level from the top of the screen (except

for Pokemon pushed off the top of the screen) in random positions (although

more/less equally) from any Pokemon available in the level.

Rare Pokemon will occasionally appear too, except these Pokemon will

dissapear after being on the bottom screen for a fixed length of time.

As far as we can tell, these are also totally random, and the rare Pokemon

are listed in order of rarity.

When you complete a level, you get a certain number of bonus points,

depending on how many Pokemon you have left on screen.

0 Pokemon  20,000 points
1 Pokemon  10,000 points
2 Pokemon   5,000 points
3 Pokemon   2,000 points
4 Pokemon   1,000 points
5+pokemon       0 points

You also get bonus points whenever you clear the screen, 10,000 points for

each time you do it.  This helps you meet the stage goal and gain prize

coins.

A level ends when you have Trozeied the number of Pokemon mentioned at the

beginning of each level.  If, at the end of the level, you have the number

of points mentioned at the beginning of the level, you also get a prize coin.

These coins are spent in the junkyard, after fighting the third boss.

Your goal, alongside rescuing pokemon, is to fill up your pokedex.  You can

get a silouette by entering a level that a pokemon is found in, or 'seeing'

them.  You can fill in that spot by catching that pokemon.
