Organized Play

Premier

Run by Riot Games or by an official organizer, with names and features of their own.

Qualifier

Any competition offering rewards or access to a premier event. This is the rung that carries you upward.

Local

Anything that is neither of the above. Mostly the weekly night at a shop, and where almost everybody starts.

Pre-Rift

The prerelease event. You are handed packs and build from what you open, which makes it the single easiest event for a newcomer to enter, because nobody has a practised deck either.

Nexus Nights

The weekly night. A shop can run it as 1v1, as 2v2 or as a free for all. It is casual and does not feed the competitive ladder.

Summoner Skirmish

The bottom rung of the actual competitive ladder in 2026, played with a deck you built. It is the first event that feels like competition.

Summoner Skirmish used to award a first round bye at Regional Qualifiers. That has been discontinued; the remaining Skirmishes through the Radiance set still run, with larger prizing instead.

1. 1

   Regional Qualifier

   Open to all

   No qualification required at all: buy a badge and play. This is the real front door for anybody wanting into competition. The first one was held in December 2025.

2. 2

   Regional Championship

   Qualification required

   The next level up, reached by performing at the level below. The first was held in October 2026.

3. 3

   Worlds

   Qualification required

   The end of the competitive season, reached through the Regional Championship level. The first one is scheduled for 2027.

Alongside the official ladder, the Riftbound Showdown Series is run by third party tournament organisers across many regions. It is serious competition that sits outside these three rungs.

1v1 Constructed

A main deck of exactly 40 including your Chosen Champion, one Legend, 12 runes, and exactly three Battlefields with no two sharing a name. This is the format of every premier event.

Limited and Sealed

Six booster packs, a 25 card main deck, and a choice of any three domains or one domain plus the domains of a Champion Legend you opened. Every card you did not play is automatically your sideboard.

Swiss and Playoff

Swiss rounds pair by standings, with around fifty minutes recommended per round and matches typically best of three. Playoff rounds are single elimination and untimed where possible.

2v2

Supported as a casual event format, and it has a ban list of its own separate from ordinary Constructed. Check that list before you take a deck to one.

• Riot announced English language Riftbound distribution into Southeast Asia, and Thailand is among the countries named in that announcement.
• Organized Play is administered through UVS Games rather than by Riot directly. A shop wanting to run sanctioned events goes through UVS.
• The official store and event locator has Thailand as a selectable country. Its results load from their own system, which is why we print no store count and no event list here: a number like that would be wrong within weeks.
• No premier event has been held in Thailand. The nearest one is in Singapore.

Find a shop or an event near you through the official locator. Select Thailand in the filters and it will always answer with what is current.

Nexus Cup

A new monthly store tournament with a local champion, deliberately kept outside the competitive ladder.

Riftbound Challenge Series

Replaces Summoner Skirmish as the bottom rung of the competitive ladder, running at a curated network of shops rather than at every shop.

Riftbound Regionals

Renamed from Regional Qualifiers, with roughly three to four per set and a more even spread around the world.

Riftbound Continentals

Replaces Regional Championships. Four marquee destinations a year, one tied to each set, run over three days with an open day one qualifier so anybody can play in.

Riftbound World Championship

The season finale, closing the system as it does now.

Shops begin moving to a new platform called the Riftbound Gaming Network from 14 Sept 2026, expected to be in use for the Radiance set's events onward.

Summoner Skirmish keeps running through the Radiance set and then retires. If you want to play that format, this is the last season for it.
