Quick answer: Princess Gambit is a Clash Royale Global Tournament running September 21-26, 2026 in Season 87 "Minion Academy". It is a sudden-death battle with only two Princess Towers and no King Tower, played with a rotating deck of 40 cards capped at Level 11; Evolutions and Heroes are always active and drawn from your own Collection. Rewards are an exclusive badge plus a Leaderboard Finisher Badge for the top 10,000 players. The mode first ran June 10-20, 2026 in Season 84 without a published ruleset.
Princess Gambit returns September 21-26, 2026 as a six-day Global Tournament inside Season 87 "Minion Academy" (September 7 - October 5, 2026), and for the first time Supercell has published its ruleset: sudden death, two Princess Towers and no King Tower, a rotating 40-card deck, Evolutions and Heroes always active, and every card capped at Level 11. The exclusive tournament badge is joined by a Leaderboard Finisher Badge for the top 10,000 players.
What Are the Princess Gambit Rules in September 2026?
Princess Gambit's rules, as stated in Supercell's "New Season: Minion Academy!" release notes:
| Rule | Detail |
|---|---|
| Format | Global Tournament, September 21-26, 2026 |
| Win condition | Sudden death — the first tower destroyed ends the match |
| Towers | Two Princess Towers only; no King Tower ("Tower Princess is back on top while the King enjoys the end of his summer vacation") |
| Deck | A rotating deck of 40 cards; you see which cards and forms are available at the start of each battle |
| Evolutions and Heroes | Always active; availability is based on your personal Collection |
| Card levels | Available cards capped at Level 11 |
| Rewards | Exclusive badge; Leaderboard Finisher Badge for the top 10,000 |
Two consequences follow. First, the Level 11 cap removes card-level advantage, so a maxed account and a Level 11 account play the same cards at the same strength. Second, the cap does not apply to what you own: which Evolutions and Heroes you can field comes from your Collection, so a player with 20 Evolutions and 16 Heroes unlocked sees more forms than one with 3 and 2. Breadth of Collection, not depth of levels, is the account edge in this mode.
Supercell has not published the number of wins for the badge, the loss limit, or the entry cost; this page will add them once the tournament opens on September 21.

How Do I Prepare for Princess Gambit?
Impact: significant. Preparation splits into what you can do before September 21 and what to do in the queue.
Before the event:
- Unlock breadth. Evolutions and Heroes you own are the only variables the Level 11 cap does not flatten. If you are sitting on Wild Shards or Hero Coins, spend them before September 21 rather than after the tournament ends on September 26. The Evolution tier list and Hero Encyclopedia rank the options.
- Learn the two-tower map. With no King Tower, there is no tower activation, no King-Tower-range defence, and no second life for a lane. A single Princess Tower falling ends the game, so a cheap chip cycle that would be a losing line on the normal map is a winning line here.
- Re-read the season's fixes. The September 1 patch made Hero Barbarian Barrel and Hero Berserker refund Elixir if they die before their ability fires, and fixed Evolved Hunter's net against a jumping Mega Knight — both matter in a mode where a single defensive misplay loses the match.
In the queue:
- Read the 40-card pool at the start of every battle. The available cards and forms are shown before the match; a pool without a heavy tank rewards cycle, a pool full of splash rewards single-elixir bait.
- Defend the tower that is being attacked, not the lane you want. Sudden death punishes counterpushing through a damaged tower.
- Treat Heroes as the swing. With levels equalised, a well-timed Hero ability is the largest single stat swing available.
What Was the June 2026 Princess Gambit?
Impact: small. Princess Gambit first ran June 10-20, 2026, a ten-day slot inside Season 84 "Stone Cold" (June 1 - July 5, 2026), built around the Evolved Princess that Season 84 shipped. Supercell did not publish a rules page for that run, and the earlier version of this guide recorded only what could be sourced: the window, the theme, and the balance context (the June 1, 2026 patch cut Tesla's lifetime from 30 to 25 seconds).
Several rules circulated for the June run without a source — a removed King Tower, a first-Princess-Tower-destroyed win condition, a randomized 40-card pool, a League Badge at 15 wins, and a Leaderboard Finisher Badge for the top 10,000. The September 2026 release notes confirm the first three and the top-10,000 badge as the mode's current rules; the 15-win figure remains unpublished and is not stated here. Whether the June run used the same ruleset is still not documented by Supercell.
