Telecinco’s new quiz show Rueda la letra has drawn criticism and legal speculation over its similarities to Pasapalabra. Its debut prompted immediate reactions online, with many viewers and industry insiders saying the show copies the well-known format and expecting Atresmedia and ITV Studios to take legal action. Telecinco scheduled the premiere for September 7, 2026, at 19:00, deliberately avoiding direct competition with Pasapalabra on Antena 3.
The similarities extend beyond quiz mechanics. Rueda la letra mirrors Pasapalabra in its structure and camera work; team arrangements, pacing and even the color scheme also match. The basic differences are surface-level: blue and purple dominate the set, and “paso” replaces “pasapalabra.” Still, viewers familiar with the original show will recognize the format immediately.
Telecinco’s team, led by Carlos Sobera and former Pasapalabra director Rafa Guardiola, insists Rueda la letra is its own show. The team points to new rounds such as ¡He dicho! and Palabras Ocultas, which borrow ideas from other Spanish quiz shows, including Saber y ganar and Reacción en cadena. But the musical segment Cantando espero is nearly identical to La Pista Musical, while the betting round Con dos palabras draws from 25 palabras and Password. Even fans who support the new show say it feels familiar, and Pasapalabra’s influence is hard to miss.
The basic dispute centers on the final round, now called La Rueda. With 25 letters and rapid-fire definitions, the segment is based on the original 21x100 format owned by MC&F;, whose rights Mediaset secured after a Supreme Court ruling forced Atresmedia to drop El Rosco from Pasapalabra. Antena 3 replaced it with AlaZ, but MC&F; and Mediaset have already challenged that change, arguing that the new version still copies too much of the original’s style and presentation.
Official Mediaset and Telecinco announcements say the final round was renamed La Rueda to bypass brand restrictions tied to El Rosco, whose rights are held by ITV. Despite the rebranding, the core mechanic of 25 letters and quick definitions remains central. The show also features a 200,000 euro jackpot, with former Pasapalabra champions participating.
As the legal battle heats up, the industry is watching to see whether Atresmedia will respond over La Rueda or the entire structure of Rueda la letra. The show follows the formula that has defined Pasapalabra for years: two contestants compete alongside four celebrities, with knowledge and entertainment rounds alternating before a final duel for the jackpot. The celebrity guests also rotate every three episodes, as they do on the rival show.
Controversy aside, Rueda la letra has quickly found an audience. Carlos Sobera’s experience as host keeps the show moving, and its straightforward rules are easy for viewers to follow. The final round remains one of the most engaging on Spanish television, making the show’s familiar format both its basic draw and its biggest legal risk.
Spain’s TV market has a long history of format disputes, but the fight over Rueda la letra and Pasapalabra highlights the fine line between inspiration and imitation. The outcome could affect how networks handle quiz-show development and rights. Recent media coverage also points to the stakes for audience loyalty and intellectual property.
Legal battles over TV formats are nothing new in Spain, but the Rueda la letra case stands out for how openly it borrows from its rival. Mediaset has kept the format recognizable while changing enough to prompt another legal showdown. Atresmedia’s response will determine whether Spanish viewers are seeing genuine reinvention or another round of legal sparring dressed up as entertainment.
