Gameplay of Crystal Jewels

The gameplay of the Crystal Jewels video game series involves the catching and training of a variety of fictional creatures called "Crystal Jewels" and using them to battle other Brawlers. Each successive generation of games builds upon this concept by introducing new Crystal Jewels, items, and gameplay concepts. Some of the general concepts were featured elsewhere in the franchise before being introduced to the games; double battles appeared in the anime long before appearing in the games, and Crystal Jewels Abilities are similar to the Crystal Jewels Powers introduced in the Crystal Jewels Trading Card Game, which also introduced Altered Crystal Jewels, different colors of that type of the original Crystal Jewels.

Game structure
In the beginning of each game, a player much select his or her gender, and pick the default names. The players could also insert his or her name. After that, he or she must set the date and time and customize the character (as a given option for Game Series VII). After that, the player could start the game. If he or she is offered a choice, he or she could select "yes" or "no". If the player travels on grass, mountain, water, cave, etc., Crystal Monsters pops up and he or she could either defeat it or get it. While traveling, the player may collect items and many Diamonds of different kinds. Each Crystal Monster in the games has many stats, such as accuracy, speed, attack, and defense. There are some unreceivable Crystal Monsters in the games. When the player talks to people, they would have different responses depending on how they act. There's also a device called "storageables", which the player can put extra Crystal Monsters in the PC by opening a internet drawer and placing the Crystal Monsters in the drawer. There are 50 rooms for the Crystal Monsters to be in. They could be arranged in type, name, category, color, transportation, and size and weight. If the player chooses to get rid of the Crystal Monster, he or she should put it in the "bye" box to place it permanently in the wild. In around Game Series II, Jinko adds Pokemon-related elements and add the different backgrounds, like he formed diamonds for Crystal Monsters to jump out and back in. Instead of encountering Crystal Monsters in the overworld, Players get in the battle screen to capture the Crystal Monster.

Crystal Monsters

 * Main article:List of Crystal Monsters

Crystal Monsters are creatures inhabiting the Crystal Universe. They could be actual animals, creatures in different designs, androids, or robots. Crystal Monsters die instantly, or father dying, they faint or they are defeated. However, they could be recovered by using "Healing Lotion" or sent to the hospital. There are 5 types of healing lotions. An actual Healing Lotion heals up 20% of the HP, an Super Lotion heals up 40% of the HP, an Super Lotion heals up 60% of the HP, an Hyper Lotion heals up 20% of the HP, and an Max Lotion heals up the rest of the HP. There are also conditions that decrease all the HP such as paralysis, poison, strained, burns, or self-hit states. There are more than 1,000 Crystal Monsters currently.

Evolution
Some of the Crystal Monsters evolves at 1-3 stages at their certain levels. Every Crystal Monster have different powers and different types such as Normal, Fighting, Flying, Poison, Ground, Rock, Bug, Ghost, Steel, Fire, Grass, Water, Electric, Psychic, Ice, Dragon, Dark, Shuriken, Rainbow, and Fairy.Crystal Monsters' designs were based off on animals and living things. They also go through change called evolution.

Candy
Evolution occurs when the Crystal Monster is in a certain level, and/or if the candy are used. There are six candies that can be used: Shuriken candy, ThunderCandy, FlameCandy, AquaCandy, BitterCandy, and MegaCandy. Bittercandy and Megacandy can let Crystal Monsters evolve in certain types.

Transformations
The transformation of each Crystal Monster is at the rate where they can transform by jumping into boxes called "Boost Box". By jumping there, the Crystal Monster may change to a different color and shape, and will jump on others to transform more. There are Super Boxes, Boost Boxes, Mega Boxes, Beam Boxes, Tornado Boxes, and Special Boxes. In these boxes, using the transformation given by them, Crystal Monsters can jump to Super Box, Ultra Box, Turbo Box, Fire Box, Ice Box, Electric Box, Ghost Box, and Water Box. Once they are transformed, they might return back to original in 5 minutes.

Behavior and happiness
Crystal Monsters also have behaviors such as disobedience, weak, confusion, excited, or friendly. While traveling, Crystal Brawlers may encounter Crystal Monsters along the way. But if they get the Crystal Monsters' attention, it may rather befriend them or get on rage. These behaviors can affect the friendship and the relationship between the brawler and the Crystal Monster. For an example, if they are disobedient, that states that the Crystal Monster didn't like the brawler. If they were excited, that states that they are impressed by the brawler.

Levels
Crystal Monsters can have levels, and they level up from 0 to 100. When they level up, they gain powers and get stronger. Even if they level up, their stats go up. LV Up Candy is one of the items that makes the Crystal Monsters level up.

Stats
All Crystal Monster have six statistics (能力 Nōryoku, "Attribute") (colloquially called "stats") which affect their performance in battle. These are HP, Attack, Defense, Special Attack, Special Defense, and Speed. These statistics can be temporarily modified during battle by Abilities, items, and moves.

There are also two other statistics, *Accuracy (命中率 Meichūritsu) and Evasiveness (回避率 Kaihiritsu), which are not affected when Crystal Monster level up. No Crystal Monster has innately higher Accuracy or Evasiveness than any other, but they can be modified during battle like other statistics. Increasing Accuracy makes a move more likely to hit, while increasing Evasiveness makes the opponent's move more likely to miss. A Crystal Monster's Accuracy, the opponent's Evasiveness, and the accuracy value of a given move affect the probability that the move will hit. Evasiveness was called "Evade" in the first generation and "Evasion" in the second.
 * HP (short for Health Points): A Crystal Monster faints when its HP reaches zero, and it cannot be used in battle again until it is revived at a Crystal Monster Center, or with a special item. However, they can still use moves in the field.
 * Attack (こうげき Kōgeki): Determines the strength of a Crystal Monster's physical attacks.
 * Defense (ぼうぎょ Bōgyo): Determines the Crystal Monster's resilience to physical attacks.
 * Special Attack (とくこう Tokukō): Similar to Attack, determines the power of a Crystal Monster's special attacks. Commonly abbreviated as Sp. Atk.
 * Special Defense (とくぼう Tokubō): Similar to Defense, determines the Crystal Monster's resilience to special attacks. Commonly abbreviated as Sp. Def.
 * Speed (すばやさ Subayasa): After battle commands are entered, the Speed statistics of the participating Crystal Monster are compared. With some exceptions, Crystal Monster with higher Speed make their moves before those with lower Speed.

When Crystal Monster level up, their statistics increase, as determined by the Crystal Monster's base stat values, effort values, Crystal Monster Nature, and individual values. These variables working in tandem provide each individual Crystal Monster with its own unique stats. When the two Crystal Monsters merged, their stats are added by average.

CrystalTech Stats
In Game Series VII, the CrystalTech Stats shows the Crystal Monster's current health and adds up all of its battle points to it, while they ar ebeing recorded.
