Prison Break: The Deserted Island Game

[Prison survival + Squid Game + revenge + mild horror + mystery + no wish fulfillment]

(1) The prison is on a small island in the South Pacific. Two cargo ships bring supplies to the island every two weeks, and the warden appears once a month.

(2) The island has two prisons, a signal tower, a villa, and a brightly lit building whose purpose is unknown.

(3) Every fifteen days, all prisoners must be injected with an unidentified liquid.

(4) Every month, fifty people are chosen at random to take part in a game. The top five winners get to spend two days enjoying themselves at the villa.

(5) New prisoners only arrive at the prison when someone dies.
