Reference table when working with bit masked or "packed" values:

Logical Operation	WebAssembly	Bitmask Action
AND	i32.and	Query the value of a bit
OR	i32.or	Sets a bit to true (1)
XOR	i32.xor	Toggles the value of a bit

Assigning meaning to the bits of an integer on a checkerboard:

Binary Value	Decimal Value	Game Meaning
[unused 24 bits]...00000000	0	UnOccupied Square
[unused 24 bits]...00000001	1	Black Piece
[unused 24 bits]...00000010	2	White Piece
[unused 24 bits]...00000100	4	Crowned Piece

Truth table illustrating how the game works

Value	Meaning	Operation	Mask	Result
0101	Crowned Black	&	0011	0001 (B)
0001	UnCrowned Black	&	0011	0001 (B)
0110	Crowned White	&	0011	0010 (W)
