Variants of Wythoff's game translating its P-positions
Nhan Bao Ho
We introduce a restriction of Wythoff's game, which we call F-Wythoff, in which the integer ratio of entries must not change if an equal number of tokens are removed from both pile…
Two variants of Wythoff's game preserving its P-positions
Nhan Bao Ho
We present two variants of Wythoff's game. The first game is a restriction of Wythoff's game in which removing tokens from the smaller pile is not allowed if the two entries are no…
A restriction of Euclid
Grant Cairns, Nhan Bao Ho
Euclid is a well known two-player impartial combinatorial game. A position in Euclid is a pair of positive integers and the players move alternately by subtracting a positive integ…
The game Max-Welter
Nhan Bao Ho
On a semi-infinite strip of squares rightward numbered with at most one coin in each square, in Welter's game, two players alternately move a coin to an empty squ…
On the expansion of three-element subtraction sets
Nhan Bao Ho
We study the periodicity of nim-sequences for subtraction games having subtraction sets with three elements. In particular, we give solutions in several cases, and we describe how…
