The eleventh season^[1] of the popular reality show Survivor Greece, premiered on January 7, 2024 on Skai TV^[2] in Greece and (via simulcast) Sigma TV in Cyprus. Giorgos Lianos returned as host for his sixth consecutive season. Broadly following the format established by earlier seasons, a team of civilians named the Machites ("Fighters") and a team of celebrities named the Diasimoi ("Famous") are invited to compete against one another for several months in a series of physical challenges on a deserted island at the exotic La Romana in the Dominican Republic. The competitors are only permitted to bring a very minimal amount of clothing and basic food supplies.

For the first time in the programme's history, the producers decided to alter the elimination process such that competitors would be eliminated by athletic challenges instead of by viewer votes.^[3]

The game began with twenty competitors divided equally into two teams of ten: the civilian Machites, colour-coded in blue, and the celebrity Diasimoi, in red. Three of the ten initial Diasimoi members – Alexis, Asimina, and Katerina – were competitors in earlier Survivor seasons.

At the beginning of week 3, four additional competitors joined, with each team gaining two: Daniel Nurka and Zoi Asoumanaki joined the Diasimoi, and Aira Adomaityte and Sotiris Lamai joined the Machites.^[4]

A total of six new competitors joined the competition in week 6. In episode 21, each team gained three new players: past season contestants James Kafetzis and Stavroula Chrysaeidi both joined the Machites along with new contestant Kostas Vougioukalakis, while Elena Amanatidou and Thodoris Tourkogeorgos went to the Diasimoi.^[5] When Kostas fell ill and was taken to hospital after competing in only one match, he was removed from the competition in episode 22 and replaced by Giorgos Gioulekas.

Four new contestants joined at the start of week 8 (episode 29). Evgenia Borla, Anastasia Tserou, and Nikos Rikounakis all went to the Diasimoi, while Christoforos Taxidis joined the Machites, meaning that at that point in the game, there were 11 Diasimoi and 12 Machites.

Two new male contestants entered at the beginning of week 9 (episode 33): Giorgos Papacharalampous joined the Diasimoi and Pantelis Giannakakis joined the Machites.

At the start of week 10 (episode 38), the two teams were shuffled and had their "Diasimoi" and "Machites" names dropped in favour of exclusively referring to both teams by the colours with which they were coded. Giorgos Gioulekas, Fanis, Giannis, Christoforos, Ioanna, and Aira were moved from the Machites to the new version of the Red Team, while Giorgos Papacharalampous, Savvas, Daniel, Thodoris, and Evgenia moved from the Diasimoi to the new Blue Team. The other players stayed at their original teams.

A second reshuffle happened at the start of week 11 (episode 43), whereby Fanis and Anastasia from the Red Team were switched with Giorgos Papacharalampous and Dora from the Blue Team.

¹ In episode 29, the second task was a footvolley match between pairs of contestants (both Diasimoi and Machites) and a team consisting of Acun Ilıcalı (owner of Survivor Greece production company Acun Medya) and Brazilian football legend Ronaldinho.

At the ends of three out of four episodes, whatever team lost the episode's immunity match must vote to nominate one of their teammates to compete in that week's elimination challenge. These elimination challenges were newly introduced for this season, replacing the viewer votes that had previously determined who would be eliminated from the competition each week.

In the third vote of each week, once the team votes have been cast and a third nominee chosen, the gender group majority of those three nominees determines the gender of all competitors who will compete in the elimination challenge, since all competitors entering the elimination challenge must be of the same gender to avoid unreasonable gendered physiological inequality between the challengers. If all three nominees are of the same gender, no further team voting is required. Otherwise, the nominee who does not belong to the gender of the other two is automatically removed from the challenge, and a second vote for that episode (and final one for that week) is cast to nominate an appropriately gendered challenger to replace them.

Once three team-voted nominees of the same gender group have been determined, one "MVP" competitor – chosen based on their performance statistics for the week – nominates a fourth and final challenger from their opposing team (who must also belong to the previously determined gender group). The MVP also selects the specific task that will form the basis of the elimination challenge.

Finally, the four challengers compete in the elimination challenge set by the MVP. They initially compete in pairs, with each pair's winner securing their ongoing participation in the competition. The losing challengers of each pair then compete against each other to determine the overall loser of the challenge, who is then eliminated from the competition.

There was a format change in week 9 necessitated by the addition of a fifth weekly episode from that point onward. Since there would henceforth be four rather than three episodes of matches with an elimination vote at the end, the MVP would no longer nominate the fourth elimination challenge player. The MVP would, however, continue to be recognised and choose the task used for the elimination challenge. Additionally, if any vote were to result in a tie, the MVP would be given the final decision on which of the tied players to nominate for the elimination challenge.^[9]
