Pokémon Go has only been released a day ago, but Singaporeans are already out in full force trying to catch 'em all.

The point of the game is simple: the higher the level of your trainer, the greater your chance of finding rare Pokémon, and the stronger you become.

If you are near a body of water, you might see water Pokémon. Going out to hunt at night might get you some cool nocturnal Pokémon, like Clefairy and Gastly. Some Pokémon appear in certain places more often than other Pokémon.

So if you're not familiar with the Nintendo game, you might not know your Rattatas from your Laprases, or your Onixes from your Snorlaxes.

For all you know, you might have unwittingly caught a super-rare Pokémon without realising it, too — and to help you with this, Reddit user RotomGuy has created this useful Pokémon Rarity Chart:

This list lets you know which are the rare Pokémon you should be saving your Pokéballs for.

Here are the names of the Pokémon listed:

Everywhere

Rattata, Pidgey, Weedle, Caterpie, Drowzee

Region exclusive

Not currently available

Ditto, Moltres, Zapdos, Articuno, Mewtwo, Mew

All five legendary Pokémon and Ditto are listed as "Not currently available" — they have neither been found nor been caught yet. Currently, the number of Pokémon in the game stands at 145. When these six Pokémon are made available, they will complete the 151 monsters from the original game series.

This means that as far as prevailing wisdom goes, we might not be able to catch them all just yet.

In the meantime, we can aspire to be like Nick Johnson.

On August 5, the 28-year-old from New York became the first Pokémon trainer confirmed to have caught all 145 Pokémon currently available in the game. According to this Mashable report, Johnson did an amazing feat of catching all 142 Pokémon available in the US in just two weeks, covering some 152km on foot and hatching 303 eggs.

Two companies, Marriott Rewards and Expedia, who were impressed by his dedication and effort, sponsored a round-the-world trip (!) for Johnson to catch Pokémon not found in North America.

Johnson became the world's first Pokémon master when he completed his collection of 145 Pokémon in Sydney, capturing a rare Kangaskhan (exclusive to Australia and New Zealand).

For now, at least we know which are the rarest Pokémon that will bring us one step closer to being like Johnson the very best.
