Hint: Getting Mewto:

To get Mewto, the rarest of all Pokemon (#150), defeat Pokemon League, and enter the cave in Cerulean city. Mewto is located deep within the cave.

Hint: Old man on roof:

Step to the right of the door at the gym where you get the Volcano Badge. You should be on the edge of the water. Use Lapras to surf out into the water. Then, come back in and go to the door. The game will say that the door is locked. Look on the roof to find an old man.

Hint: Easy experience:

An easy way to earn experience for a weaker Pokemon is to put your lowest-level Pokemon at the top of your list. When a fight begins, it will be the first Pokemon released. Instead of fighting, just switch to a stronger Pokemon. The weaker Pokemon will share the experience from the battle without being put in any danger. This is a good way to make your Pokemon gain experience evenly.

Hint: Winning money in Celadon City:

Enter Celadon City and get the coin case from the man in the back of the diner. Go to the slots and ask for some free coins. You will use these to play the slots and win Pokemon prizes. Here is how to find the slot machine that pays out the most. When you walk in, there are rows of slots. Find the man to the far left that says "wins come and go". Below him is a machine that is out of order. Play the machine directly beneath it. Do not get frustrated if you do not win constantly. If it stops paying out a lot, leave, go train your Pokemon, and come back later.

Hint: Teleport:

An Abra is hard to catch, but it is worth it. When your Pokemon are weak and you need to get to a Pokécenter quickly, press Start and choose Pokemon. A list of your Pokemon will appear. If you have Abra with you, choose him and select teleport. Note: You have to be outside first; use an escape rope if needed. It will take you directly to the last Pokemon Center visited.

Hint: Other ways to get to a Pokécenter:

Besides teleporting, the following methods may also be used to get to a Pokécenter. Use Dig when in a cave; Fly (HM05 that lets you fly to any desired town; Also try Softboiled that you can only teach Chansey. It takes some of Chansey's health to give to another Pokémon, and also restores Chansey's health by half during a battle. Flash, used to light up Rock Tunnel and make an opponent's accuracy fall. Cut used to cut certain bushes and is used like Scratch in battle. Surf, which lets you surf across any body of water and is used like the Hydro-Pump in battle.

Hint: Keep earning money:

Here is a great way to keep getting money even after beating all the trainers in the game. Keep betting the Pokemon league 4 and your rival repeatedly. You can beat them an unlimited number of times. This is also a useful to build levels quickly.

Hint: Fight Safari Pokemon elsewhere:

This trick allows you to fight Pokemon from one area of the game in another area. For example, go to the Safari zone and battle for a while. Fight a Taures, then leave the Safari zone. Then, go to the island where Articuno is found. Swim up and down the shore, at the point where it appears that you are on the ground, but are actually swimming in the water. Monsters from the Safari zone will appear here.

Hint: Unlimited chances to catch rare Pokemon:

First ,find a rare Pokemon such as a Mewtwo. Then, immediately before entering a battle with it, save the game. Now you can battle the Pokemon without worrying about not catching it. If you make a mistake and make it faint, stop and shut off the game. Then, turn on the game and use the continue option to restart just before the battle.

Hint: Unlimited time for Safari zone (Water Pokemon only):

This trick allows an unlimited amount of time in the Safari zone to catch Water Pokemon. Obtain a good or super rod. Next, go to the Safari zone and find some water. Then, go into inventory and use the rod to start fishing. If a "Not even a nibble" message appears, press A, then quickly press Start. If you got into a fight, check the Pokemon out. If it is one you do not have, catch it then quickly press Start after the battle. Return to the inventory and fish again. If you already have this Pokemon, run from it, then quickly press Start and begin fishing again. This will help you catch some good Water Pokemon with plenty of time.

Hint: Better chance to capture Pokemon:

When you throw a Poke-ball hold A as it closes on the Pokemon. The Poke-ball will shut tighter, making it easier to catch the Pokemon.

Hint: Harder hitting attacks:

Hold A while attacking to do more damage.

Hint: Clone Pokemon:

Note: This trick requires someone with another Game Boy and Pokemon game. Trade the Pokemon to be cloned, and have the other player get a Pokemon that he or she does not care about. Trade them, and make sure the player receiving the bad Pokemon can see the other player's screen. When the Game Boy that receives the good Pokemon's displays "Waiting", get ready to shut the other Game Boy off. When the "Waiting" message disappears, turn off the Game Boy that is receiving the bad Pokemon. When the "Trade completed" message appears, turn off the remaining Game Boy. Both games will have the same good Pokemon when they are turned back on.

Hint: Rare bird Pokemon locations:

Moltres (Victory Road), Articuno (Sea Foam Isle), Zapdos (Abandoned power plant).
