Ok, I'll try to give you a quick visual

Lets use a 3-cell array

Cell 1 - 4 bytes/32 bits - 32 bits total
A single cell is perfect for player booleans since player ID's range from 1 to 32.
[ 0000 0000 ][ 0000 0000 ][ 0000 0000 ][ 0000 0000 ]

Cell 2 - 4 bytes/32 bits - 64 bits total
[ 0000 0000 ][ 0000 0000 ][ 0000 0000 ][ 0000 0000 ]

Cell 3 - 4 bytes/32 bits - 96 bits total
[ 0000 0000 ][ 0000 0000 ][ 0000 0000 ][ 0000 0000 ]

When you want to set bits beyond 32, you need to use an array, cell 2 holds bits 33 to 64, cell 3 holds 65-96, etc. Those macros do the work for you to set the appropriate bit.
