|Title||Games based on region crossing changes|
A region crossing change at a region of a link diagram is defined to be the crossing changes at the crossing points on the boundary of the region. In this talk, we show that the region crossing change on a knot diagram is an unknotting operation. Using this algorithm, we introduce the game ``Region Select'' and its dual game ``Region Lighten'' as a joint work with Akio Kawauchi and Kengo Kishimoto. Let's enjoy !
