One hundred one words take A in the second box and M in the third. They fall into two branches that barely resemble each other.
Thirty of the one hundred one take E in the fourth box, which gives you the easy words like GAMES, NAMED and CAMEL. Another twenty nine take B or P instead, and those sound and look completely different. CAMPS, LAMPS, LAMBS and RAMPS all belong to that harder branch.
Which branch you are in matters more here than the first letter, because the two share almost no endings.
Thirteen of these open with G. C has eleven, S has ten and L has nine. Nineteen letters appear in that box, so the first box gives you very little to work with.
Twelve words repeat the M, and GAMMA and MAMMA are the two most people know. If you have A and M confirmed and a second M is still possible, that branch is short enough to work through by hand.
Yes, it is a dance and a style of music. SAMBA sits in the same group and takes the same B in the fourth box.
Thirty five do, thirty five percent of the group, mostly plurals of CAMP, LAMP and GAME.
It fits the rule exactly, running G, A, M, U, T. Only five words take U in the fourth box, which is why GAMUT is so easy to overlook.
