Having an unreliable gaming group, I often don’t know if two friends or 6 will show up for a game night. One of the selling points of Space Alert was the “1-5” players advertised on the box. While I absolutely love the game with 4-5 players, to my disappointment it is not a 1-5 player game. The 1-3 player experience felt like tacked on, where each player just plays the role of 2 or more people.
To rectify this situation, I made a new board designed for a 1-3 player experience (similar to the idea of using a different board for smaller games in Small World). I dubbed the ship Little Duckling. Simply print and mount the board (on the back of the Sitting Duck if you really like it)
The rules (with examples and clear diagrams) and a complete set of missions (from tutorials through simulations to missions) are included in the Little Duckling handbook.
This has been play tested and I hope produces a balanced and fun 1-3 player experience for you as well.
