Similar in design to the later Mario Party titles, players begin by choosing one of three of the undercover cops.
The player begins at the start location of the board and must use one of their "numbered value tiles".
If the number chosen is above 1, the player must compete on a slot machine to try to win a value up to what was written on the tile.
Following that, the player is able to move the number value, which they have won, of spaces on the board.
Certain squares will activate events that include talking with characters, buying items and engaging in battle.
Battles with enemies are handled by each side choosing one of the numbered tiles they own.
The party with the higher number becomes the attacker and the lower value becomes the defender.
Each side then chooses another numbered tile to determine the amount of "effort" put into the attack or defense as well as a position of the body to attack/defend.
With that chosen, the turn's sequence plays out, with HP lost on a successful impact.
Upon defeating an opponent in battle, the player gains XP and gold.
About Game Boy
The original Game Boy (1989) proved that handheld gaming didn't need cutting-edge graphics to succeed — its monochrome screen and legendary battery life, combined with Tetris as a pack-in, made it a cultural phenomenon. Game Boy cartridges are famously durable, so this remains one of the more accessible retro platforms to collect, though translucent color variants and complete-in-box copies with the original brick-sized manual add real value for condition-focused collectors.
Gamevaro tracks Undercover Cops Gaiden for Game Boy with separate market values for loose, complete-in-box (CIB) and factory-sealed copies, sourced from real eBay sales. Prices also vary by region — PAL, NTSC-U and NTSC-J releases of the same game often sell for different amounts due to print run sizes and regional collector demand.
Adding Undercover Cops Gaiden to a Gamevaro collection takes seconds — search by title or scan the box barcode, and the app fills in cover art, release details and current pricing automatically. This GB release dates back to 1993.
