All participants are divided into teams of five, the teams taking part in a knockout tournament.
The participants from each team to take part on each match are previously decided, always in the same number from each.
A gemstone is placed in the site of the match and the team who takes it first wins.
According to Rita, the team who wins the tournament will have one wish granted.
In addition, the site of each match appears to be protected by a kind of magic barrier and all contact with the external world is cut. The participants also are prevented from summoning allies in the battle, like when Go-on Red failed to invoke Speedor.
No members of any Dinosaur-themed Sentai Teams participated in the tournament, they were represented only by the then upcoming Ryusoulger's Ryusoul Green and Ryusoul Black (who for an unspecified reason were forcefully summoned to Nemesis), who were not true participants.
Of the 160 characters participating in the tournament:
The Carrangers have their entire team roster, extra heroes included, for the first time since their show, unless Sentai Ranger WannabeRadietta Fanbelt is accounted for.
The Kakurangers have their entire team roster, extra heroes included, for the first time since their show.
This occurs before the first episode of Kishiryu Sentai Ryusoulger, with Towa and Bamba already having become Ryusoulgers, unlike Koh, Melto and Asuna.
For all members of Team Oddball, this occurs after the main events of their season:
After Doubutsu Sentai Zyuohger, because Yamato was capable of fusing all three modes - Eagle, Whale, and Gorilla - which he only learned in the final battle against Genis.
After Kaizoku Sentai Gokaiger, as Marvelous is shown both talking to Yamato in the middle of Doubutsu Sentai Zyuohger and recollecting Akaranger's Ranger key.
After Uchuu Sentai Kyuranger, as Stinger is now Commander of the Rebellion and refers to Tsurugi as "President". The Kyurangers are still acknowledged to come from a different universe as Stinger traveled to the main universe after detecting a cosmic disturbance.
Whether this is before or after the "two years later" epilogue of the series is unknown.
After Ressha Sentai ToQger, since the tournament takes place four years after the ending of ToQger, Kagura is currently at age sixteen, explaining why she is appearing in her adult state.
