Battle Formats - GashiStudios

Singles

The classic duel. One Pokemon at a time. Pure strategy, no distractions.

Active: 1 Pokemon
Team: 3+ Pokemon
Style: Traditional competitive play

Fast-paced matches where every prediction matters. Perfect for players who love mind games and one-on-one showdowns.

Doubles

VGC-style 2v2 battles. Teamwork wins fights.

Active: 2 Pokemon
Team: 4+ Pokemon
Style: Team synergy and positioning

Spread moves, partner combos, and Protect mind games. The format where coordination is king.

Triples

Full-scale warfare. Three Pokemon clash at once.

Active: 3 Pokemon
Team: 6 Pokemon
Style: Complex positioning and team coordination

Position matters. Center Pokemon can hit anyone; side Pokemon have limited reach. The ultimate test of team building.

Random Battle (Randbats)

Pokémon Showdown-style Random Battle formats where the server generates your team for you. Available as RANDOM_SINGLES, RANDOM_DOUBLES, and RANDOM_TRIPLES. They use the same Singles/Doubles/Triples rules, but with a server-generated 6-Pokémon team instead of your own party.

Random Battle has its own separate rating and leaderboard, fully isolated from the regular formats. See Random Battle for the full guide.

Independent Rankings

Each format has its own:

Queue: Singles players only match with Singles players
ELO rating: Climb separately in each format
Leaderboard: Dominate one format or conquer them all
Blacklist rules: Different bans per format if configured

Matchmaking Settings

Control how players are matched within each format:

Setting	Default	Description
`enforceEloRange`	`true`	Enable Elo-based matchmaking
`initialRange`	`200`	Starting ELO range (±100 = 200 total)
`expansionDelay`	`30`	Seconds before range starts expanding
`expansionRate`	`50`	ELO added per expansion cycle
`maxMultiplier`	`3.0`	Maximum range multiplier (3× initial range)
`immediateMatchRange`	`100`	ELO range for instant matches

How range expansion works:

Start: ±100 ELO (200 total range)
After 30s: ±150 ELO (expands by 50)
After 60s: ±200 ELO (expands by another 50)
Maximum: ±300 ELO (3× initial range)

Restricted Pokemon System

Some presets use a restricted Pokemon system (VGC-style):

Setting	Description
`restrictedCount`	Max number of restricted Pokemon allowed
`restrictedPokemon`	List of specific Pokemon marked as restricted

When restrictedCount > 0, players can only include that many Pokemon from the restricted list in their team.

Gimmick Control (Mega / Z-Moves / Dynamax / Tera)

The megaEvolution, zMoves, dynamax, and terastallize toggles actually disable the gimmick in ranked battles. Because these mechanics (added by Mega Showdown) are gated by key items, simply banning the items isn’t enough. CobbleRanked blocks the gimmick at the moveset level during battle (via a mixin on the action request) so it can’t be used even if the player has the item. Casual and non-ranked battles are unaffected.

Multi-Format Rewards

Season rewards are distributed per format. Rank high in all three? Get rewards for all three.
