SOS

SOS is a game similar to tic-tac-toe. We study a variety of variations of it played on a 1-by-$n$ rectangle. On our journey we change the target string to SOO, then study all target strings containing SSS, then go back to finite strings and study SOSO. Then we create a variation with two target strings SSSS-OOOO. We continue with mis\`{e}re games. After that we look at different changes of the board: we wrap the board around, add dimension, and allow it to expand. We end with a variation that came from the ultimate tic-tac-toe.

Generalizing the Wythoff Array and other Fibonacci Facts to Tribonacci Numbers

In this paper, we generalize a lot of facts from John Conway and Alex Ryba's paper, \textit{The extra Fibonacci series and the Empire State Building}, where we replace the Fibonacci sequence with the Tribonacci sequence. We study the Tribonacci array, which we also call \textit{the Trithoff array} to emphasize the connection to the Wythoff array. We describe 13 new sequences.
