Super Sentai Battle: Dice-O is a Massive Multiplayer Crossover arcade game featuring the heroes, mecha, and villains of the long-running Super Sentai franchise. Originally introduced as a tie-in to Tensou Sentai Goseiger (that team's powers come from cards that were made with the same layout as the ones in real life at the time), the game was upgraded to Dice-O DX (Deluxe) for the premiere of Kaizoku Sentai Gokaiger, and further upgraded to Dice-O EX (Express) for Ressha Sentai ToQger.
Players scan cards to represent a team of five heroes from Super Sentai's various series, along with a Humongous Mecha and either a Sixth Ranger or a Finishing Move that will appear on a certain round. In battle, the team to attack (or attack first, in the case of EX) is decided by a roulette wheel, with the best result on each wheel allowing that team member to perform an individual Finishing Move. After a few turns have passed one or both sides will be able to summon their Humongous Mecha for a chance at doing large amounts of damage. The winner is the one to drop the opponent's Hit Points to zero.
Series represented in the game include all Super Sentai series up to ToQger, as well as Space Sheriff Gavan. The game was discontinued after ToQger.
This game provides examples of:
- Action Commands: Used all over the place, mostly causing special attacks to do more damage.
- Artifact Title: The game used to represent its attacks by six-sided dice. Now, it uses a wheel. The dice graphics are still in the game, but they're only used in two specific special move cards.
- The Artifact: On the game's website, there's a page that includes a list of all the characters and mecha from each series included in the game. For series that were included in the game during the runs of previous Sentai series, the old page backgrounds from when the teams were introduced will continue to be used. The backgrounds are even used on the individual pages for characters and mecha added in during later updates!
- Another weird example comes from the game's English localization released in some Asian countries: Power Rangers Card Battle. While the Rangers have all their names from the Power Rangers franchise, the attack names are mostly unchanged from the Japanese game, resulting in some inconsistencies- for instance, the Mighty Morphin' Power Rangers cards reference the tribes from Kyōryū Sentai Zyuranger.
- Assist Character:
- Ranger cards with secondary characters that add effects to their wheels. It started with the Go-Busters and their Buddyroids and expanded. Usually the assisting character will be a member of the same team, or else one that appeared in a crossover with that character. (The Go-on Wings have cards that include the other one in their special attacks that don't use this mechanic, however.)
- In some instances, this can allow the same character to appear twice or even three times in a line-up.
- The fourth Go-Busters set introduces combination attacks for the mecha as well.
- Boss Subtitles: When playing against villains in the single-player mode, they'll get a boss subtitle at the start of the battle. If a player or opposing team uses a complete team of rangers, that series' logo will serve as their boss subtitle.
- Combination Attack: A few of the EX Cards, and the special finishing moves of Assist Character cards.
- Contest Winner Cameo: There have been a few contests where kids got to design special attacks that would then be put into the game as promo cards. Many of these even include the original drawing as a cut-in during the attack, and they tend to be pretty strange- Gokai Red turning into a giant Ranger Key and slamming into the enemies for instance.
- Fire-Breathing Diner: One of Gokai Yellow's specials involves inflicting this on her opponents. Don't ask how they eat through the helmets...
- Five-Man Band: You don't have to build a team following the archetypes, but you always have to have five members. If you use rangers that commonly fought as a smaller group (such as Taiyou Sentai Sun Vulcan or Choujuu Sentai Liveman) you can get them to announce their team name if you use the smaller group, and the rest of the team will just fall in behind them without posing at the end of the roll call screen.
- Guest Fighter: Space Sheriff Gavan was included in the game as a promotional card after his appearance in Kaizoku Sentai Gokaiger vs. Space Sheriff Gavan: The Movie.
- Human Shield: Basco's special starts with him using one of your team as this.
- Last Chance Hit Point: On occasion, if a player runs out of Hit Points, they will be given a hundred points back due to "Sentai Spirit" and have one last chance to make a comeback. (This applies both in one-player and two-player mode.)
- Massive Multiplayer Crossover: If you've ever wondered who would win if the Kakurangers fought the Hurricanegers, or if a team of all Pinks could beat a team of all Reds, now's your chance.
- Merchandise-Driven: Of course, plenty of Sentai toys (Primarily on Goseiger ones at 1st) come with cards that work with the game, and with the "Gaburincho" sets, you can also use Zyudenchi to power up your characters.
- Number of the Beast: An example where the symbolism is clearly not intended: one version of the Sun Vulcan Robo card has an attack value of 333 on all but the highest space, which is 666 (twice as much). All of its other stats are all 3's as well, to go along with the 3 theme of the team.
- Sixth Ranger: A game mechanic, "EX Ranger Cards". If you scan one at the start of the game, a Sixth Ranger will join your team for one round, add an extra wheel to your roulette, and do a special attack.
- Super Mode:
- Regular and "super" characters get separate cards, but in some cases a normal character's Finishing Move will trigger a "Super Henshin", adding the super-version's attack on top (albeit with reduced damage).
- Similarly, some mecha have "Super Gattai" abilities that allow them to become higher-level mecha.
- "Super Sentai" Stance: Before battle begins, each team of rangers does their roll call and poses in this style, though sufficiently mixed groups can be completely non-symmetrical.
- Theme Music Powerup: When a team attacks, its leader's series theme song plays. Some other situations can cause other members of the team to have their songs play as well.
- True Final Boss: In older sets, if you did well enough in a battle on the highest difficulty, you'd end up in a "Daibattle", with stronger opponents. These often include characters who don't have cards yet; these are usually Chekhov's Gunman and will get cards in the next set. More recently these battles have just been random opponents on the highest difficulty level, rather than an extra fight.
- The Voiceless: Sometimes, newly-added rangers don't have voice clips, because the game makers are waiting for the original actors to provide them for later updates of the game. In the case of Gokai Silver, voice clips from his weapons and Gokai Cellular were used instead, while Aka Red, Beet Buster and Stag Buster just went without voices.
