Consider the cells in order, placing a queen in a cell if and only if it would not attack any earlier queen. The problem is to determine the positions of the queens. We study the problem for a doubly-infinite chessboard of size $\\mathbb{Z} \\times \\mathbb{Z}$ numbered along a square spiral, and an infinite single-quadrant chessboard (of size $\\mathbb{N} \\times \\mathbb{N}$) numbered along antidiagonals. We give a fairly complete solution in the first case, based on the Tribonacci word. There are connections with combinatorial games.<\/jats:p>","DOI":"10.37236\/8905","type":"journal-article","created":{"date-parts":[[2020,3,19]],"date-time":"2020-03-19T00:37:31Z","timestamp":1584578251000},"source":"Crossref","is-referenced-by-count":3,"title":["Queens in Exile: Non-attacking Queens on Infinite Chess Boards"],"prefix":"10.37236","volume":"27","author":[{"given":"F.
