Same license, different rules
A licensed format doesn't have to stay identical once it crosses a border — cast size, judging panels, episode counts, and release cadence are all open for renegotiation. This ranks the specific seasons where one side of a sibling pair rewrote its own rulebook loudest.

The 12, in order.
- #01A 24-player cast and a 26-episode season expand the Survivor format's original scale from the very first episode.Australian Survivor opens with 24 players across two tribes on a 26-episode run, against the American original's 16-player, 13-episode debut. The bigger cast and the longer season become the local version's defining structural signature from day one.
- #02The civilian half of the founding cast disappears, replaced by an all-reality-personality roster.Season one splits its cast evenly between reality alumni and members of the public. Season two drops that non-famous cohort entirely, shifts to a three-episode launch then weekly episodes, and adds a companion after-show — changes the UK original never made.
- #03The three-judge format the franchise has run on since its debut finally expands to four chairs.Andy Allen is joined by Poh Ling Yeow, Jean-Christophe Novelli, and food critic Sofia Levin for the format's first four-judge panel, filming three episodes in Hong Kong. The American original has never gone beyond three judges at the table.
- #04The nightly network broadcast slot gets scrapped for a daily-drop streaming release.Season four leaves CBS for Peacock, hands hosting to Sarah Hyland, and moves Iain Stirling — the Love Island UK narrator — into the American booth. What was a linear nightly appointment in the UK becomes a 38-episode daily streaming drop stateside.
- #05Mid-season intruders arrive as three brand-new couples instead of reshuffled partners.Season twelve grows to thirteen matched couples, twenty-six participants and forty episodes, the format's biggest cast yet. Adding entirely new pairs mid-run, rather than swapping existing partners, is a structural wrinkle the American original has never tried.
- #06Michelle Visage anchors the panel from the very first episode, no substitutions required.The UK edition opens with RuPaul and his longtime co-judge already fixed at the judging table across a compact eight-episode run. The American original spent its debut season rotating in a different fashion critic before she became a permanent fixture there too.
- #07Sixteen castaways and thirteen episodes set the tight original scale Australia would later expand.Borneo pits eight Pagong against eight Tagi across a thirteen-episode summer on Pulau Tiga, Malaysia. The compact cast and runtime stay the American format's enduring baseline, well past the scale the Australian version reaches from its own debut.
- #08A cast of total strangers, no recognizable faces, sets the format's original casting rule.Series one fills Ardross Castle with members of the public rather than a returning-celebrity mix, airing twelve episodes across three weeks on BBC One. The all-civilian cast remains the UK format's baseline long after the American version abandons it.
- #09A three-judge panel and thirteen episodes set the compact format Australia would later outgrow.Gordon Ramsay, Graham Elliot, and Joe Bastianich judge eighteen home cooks across a tightly compact debut run. The three-chair panel and that short season length hold as the American norm long after the Australian version expands both.
- #10A nightly ITV2 broadcast slot, not a streaming drop, sets the format's original delivery rule.Series one runs twenty-four episodes on a linear ITV2 schedule from a Mallorca villa, establishing the fire-pit recoupling and public vote the whole franchise still uses. Broadcast-television delivery stays intact years after the American version moves to streaming.
- #11Five couples and no swap-week twist mark the standardized cast size the format settled into.Houston keeps the five-couple, ten-person format and the Schwartz-Coles-Roberson panel across seventeen episodes, the third straight season built at that scale. It's the steady baseline the Australian version stacks new twists onto instead.
- #12A rotating fashion judge, not yet Michelle Visage, leaves the founding panel still unsettled.Season one plays out a short, heavily stylized batch of episodes with a different critic sitting in that seat beside RuPaul before Visage arrived. The UK edition would later open with Visage already locked into her chair from its own first episode.
