The game core of Crash Fever is not only a Puzzle & Dragons-like puzzle game, but also a hero collecting game with anime-like characters instead of dragons. You can play this by creating a party of four units to solve puzzles and defeat enemies. When questing, you defeat enemy forces and confront the antagonist until a victor emerges. Any given quest comprises separate and distinct phases that need to be performed in a similar fashion. When defeating the boss, you advance to the next stage. However, how do you direct your units to attack once they're in that stage? Explode orbs of matching color to increase your damage bonus. Also, know how the rock-paper-scissors game works. That's all you need to do to earn bonus damage. In this game, water always wins against fire. Electricity always beats grass and grass always beats electricity. If you follow this rule, everything in the game is easy to do. Questing won't earn your army any experience. You have to collect resources and labor from your subjects in order to increase your soldiers' levels. Materials, units and extra bits are periodically awarded to the player after each stage. Using these rewards, players can increase their rank and collect additional resources. During special event quests, you can earn ranks and units for a limited time. These quests need you to be at least level 30; they also require you to complete a thousand missions with Polygons given out as a reward. Buying units with money sounds expensive, but it's necessary to purchase lots of powerful units with Polygons. Polygons are also a form of currency that represents the shape of a polygon. The feature that makes this game standout is the ability to include other players in stages. You can create a room and then other players will enter it; each will play a different character. It's unclear why this is considered the primary selling point of this game, but it is definitely what makes this game stand out.

There are 11 units available in the Grad Party hatcher; they are named after different historical figures and scientists. These include Pascal, Marie Curie, Foucault, Pavlov, Galileo Galilei, Galileot, Fleming, Stokes and Swan. The available units have a detailed description below. Marie Curie rarely appears in Hatchers. She has Junk Conversion as one of her skills. To obtain her Blast Boost, collect additional units in a combo. This character has a special CP animation that no other character has. Also, she has unique weaknesses aside from her two gimmick counter gimmicks on two separate ability slots. She has a decent number of properties, but it's difficult to notice any effect on her overall performance. Pascal claims this character is interesting and appealing. She has three Turn Skill effects and a Blue Bombs drop that gives her +50 ATK and REC 2T for Blues. Stokes agrees that she’s the most ineffective character relative to her competition. He's extremely dangerous and scary, with REC Boost on his CP that drops Green Hearts as a Party CP. All of his attacks have lasers, blue to green. Besides, his animation is not attractive at all. Given her congenital paralysis, she was born with CP on Skill. Her 20B-ed can give you her full ability; however, it doubles the base ATK. Her Ability 4 increases the average damage dealt. D'Alembert further notes that she can boost her attack power by trading her usual Attack Points for Less Health Points and Recoverable Energy. While twinned, they possess a Skill with a 7-chain duration for 3 turns. This grants them 1500 more Attack Power and Red Recoverable Energy. This card has two abilities; its twin won’t work by itself. Pavlov says that this character has anti-hack which makes him a part of the Taowu Spectre combo. Foucault can boost your attack and REC by 800 when she appears.
