Gen 1

Type in the five stats on screen and the tool works back to the hidden values behind them.

A move, an attacker, a defender: the exact damage, worked out the way the game works it out.

What each trade with an in-game character really gives you, starting with the level, which the guides get wrong.

How long to wait before evolving, and what each level past that costs you.

Tick your cartridges and what you already own: the tool says what is left to catch before the Bank closes.

Which cartridges you need to catch every species in a game of its own generation.

Type in the five stats after a capture and the tool tells you whether it will be male or female once transferred.

Pick a species: the tool lists the trainers to fight so the long-range trainer glitch spawns it.

The species, the level, the HP left, and you know which ball gives the best odds and how many throws to expect.

Pick a species and your cartridge: where it appears, and your odds on each step through the grass.
