1Climb floors
Normal floors are a 1 vs 1 duel against a wild rival. Every fifth floor is a 3 vs 3 mini boss โ an elite leader with two elite partners one evolution stage below it. Floors 10, 20, 30 and onward are 3 vs 3 floor bosses โ a boss-tier ace with two partners at its own stage โ and each one awards a Crest.
2Digivolve
Your partners' level always matches the floor. At Lv 11 a Rookie becomes a Champion, at Lv 31 an Ultimate, and at Lv 51 a Mega. How it fought decides the path: a high survival rate keeps its attribute, a middling one turns it into the attribute it's weak to, and a low one into the attribute it beats. Each partner's card shows its record, the cut-offs for its stage, and where it's heading.
3Battle digivolution
Every Digimon enters battle as its Rookie form. When one runs out of HP it digivolves on the spot into the next form it has earned, with a fresh HP bar. Only its final form can be knocked out.
4Attributes
Vaccine beats Virus, Virus beats Data, and Data beats Vaccine (1.5ร damage, 0.75ร the other way). Free Digimon are neutral against everyone.
5Data Scan
Beat a rival floor and its data scatters into a Digi-Egg. From Floor 11 on, most rivals are ordinary but 15% are rare Elites and 5% are Boss-tier (Legendary at Mega) โ the only way to scan them. Call Low or High on the Digivice roll to hatch it as a new partner โ you can keep three, so a full party swaps one out. Boss Digimon belong to other Tamers and can't be scanned.
6Lives & checkpoints
You have 3 lives. A loss costs one and drops you back to the last checkpoint (Floor 1, 6, 11, 16โฆ). Beating a floor boss refills your lives. Lose all three and the adventure restarts.
7Quick quiz
Every "Enter Arena" starts with one quick question โ a math problem, or a Japanese word from the Tango module (listen, then tap the picture). A grown-up picks which on the home screen. Get it right to fight โ a wrong answer just rolls a new one.
8Friend Battle
Host a room and share the 6-digit code, or join a friend's. Bring your current partners or one of up to 3 saved teams โ you're offered a save slot whenever an adventure ends.
9Hall of Fame
Defeat the Floor 100 Champion to earn the tenth Crest, recruit a legendary Mega, and enter the Hall of Fame. Your DigiDex carries over into the next world.
