When the Pokeball hits the first three lights at the top, press Left to move the light. It can also be moved by pressing A.

Select an unevolved or basic Pokemon, then press Start to watch it move in the Pokedex. Note: This trick only works when the game is played in a Game Boy Color system.

Enter the Pokedex and press Select to view how many Pokemon have been obtained and seen.

Bonus levels are unlocked by capturing three Pokemon in the same location without getting a "Game Over" screen or changing to a different location before returning. If this is accomplished a hole marked "Go To Bonus" will appear. Enter the hole to reach the bonus level. The Red pinball machine has a Diglett's Cave bonus level, and the and blue pinball machine has a Meowth's House bonus level.

Complete both bonus stages in the machine that you are playing. In red field, clear the Digglett and Gengar stages. In blue field, clear Meowth and Seel stages. Then when you catch three more Pokemon or get a chance for another slot, you can reach the Secret Mewtwo bonus stage.

Once in the stage, hit Mewtwo as much as possible. If he is hit enough times, he will stop creating the balls. When this happens, you can hit him three more times to clear the stage. However, do not do this, since it will start the cycle over again. By leaving the Mewtwo stage uncleared, you may keep returning to it and get higher scores.

Shoot the Pokeball through the left outside loop. Each time it passes through the loop, one evolution arrow will light. When all three arrows are lit, shoot the ball into the Evolution cave. Then, choose the Pokemon to be evolved.

Shoot the Pokeball through the left loop. Each time the Pokeball passes through the loop, one evolution arrow will light. When all three arrows are lit, shoot your ball into Slowpoke's mouth. Then, choose the Pokemon to be evolved.

After entering evolution mode, quickly hit the buttons with the flashing arrows next to them. Do not try to raise Pikachu's lightning meter. The "Ball Saver" will stay lit for awhile. During this time, after hitting a button with a flashing arrow, allow the ball to move below the flippers. After the ball is launched, if the item you are looking for is near the top, you will have a good chance of getting it. Note: If this is attempted, always make sure that the "Ball Saver" is not going to run out.

Enter evolution mode. Then get the menu and select a Pokemon that has a star. Go through the entire evolution process. After the Pokemon evolves, a special evolution bonus worth 10,000,000 will be awarded.

Light up the letters C, A, V, and E to unlock the Cave bonus, but do not enter. Light up the same letters again, then enter the Cave to collect double the amount of points.

Upgrade your Pokeball all the way to a Masterball by turning on all the lights on the top half of a board. Then, try to upgrade it one more time. This is much easier than having to evolve a Pokemon with a star next to its name.

Hit a Voltorb or Shellder, then hold A or B when their shadows appear.

On the third ball, light up all the "GET" lights and enter the hole. This will increase the chance that rare Pokemon will appear.
