The player begins the game by finding himself on an uninhabited island. The island is completely empty and has no vegetation except sand and rocks and trees. However, there are plenty of fish around the island, and this may be the key to the player's survival.
In the first level, the player must create a shelter to protect himself from adverse weather conditions and find a source of food to survive the first night on the island. Over the next few days, the player must collect materials and create tools for hunting and fishing to get enough food.

At each level, the player is given a new task and new challenges, such as:

• Find and purify a source of drinking water.
  
• Create a raft for fishing.
  
• Build a conspicuous psi signal to attract rescuers.
  
• To create a system of storing supplies and protection against animals (if they appear on the island).
  
• Explore the island and discover new areas.

Each time a player completes a mission, they gain new resources, experience, and the opportunity to improve their tools and weapons. However, each new quest can be more difficult, requiring more effort and skill to complete.
The player must also monitor his health, nutrition and energy, otherwise he can die. If the player dies, he starts the game again from the first level.
The game can have different levels of difficulty and different game conditions. For example, at higher difficulty levels, more dangerous animals, weather changes, or seasonal changes such as hurricanes, tsunamis, and extreme heat may appear on the island.
Thus, the player must use his skills and knowledge to survive on the desert island and reach the end of the game.
