After saving the Aniverse with Bucky O'Hare, we’re switching to a completely different atmosphere for the fifth game of our One Credit Challenge: it’s time for Pururun, a cute and colorful puzzle game that will put your brain to the test for this 5th arcade challenge.

Pururun is a puzzle game released in October 1995, developed by Metro Corporation and published by Banpresto. Exclusively released in arcades, this relatively rare title (only 3 machines listed in the collections of active VAPS members) offers an addictive puzzle mechanic where you have to align four blobs of the same color or more to make them explode.

The title itself is a Japanese onomatopoeia that evokes a jelly-like sound, perfectly fitting for these little wiggling creatures on screen.

Universe & gameplay

In Pururun, you guide the heroes Pipi and Moko through 24 stages by making colorful blobs explode.
A particularity of the game: each blob has an outer color and an inner color. When you align four or more blobs with the same outer color, they explode and turn into their inner color. This mechanic allows you to create devastating chain reactions by planning your outer/inner combinations in advance.

The game is played in real time with a fixed top-down view, and if the grid becomes too crowded, you have a limited number of bombs to clear some space. The two-player co-op mode lets you tackle the puzzles together, adding an extra tactical dimension.

Tips to progress

The key to success in Pururun lies in anticipating chain reactions.
Don’t just pop blobs at random: observe the inner colors and plan several moves ahead to create combos. Chain reactions will not only help you reach your goal faster but also achieve higher scores.

Keep your bombs for truly critical situations when the grid becomes unmanageable—they’re your lifeline, but in limited quantity.
