Hi I need some assistance with scheduling for beer Olympics. We will have 15 teams and 7 events. I would like for each team to play each event once. If possible avoiding playing the same team more then twice. 

Thank you

Because of the odd number of teams the schedule can not be nicely balanced - so you will need to play something like this:

 E1    E2    E3    E4    E5    E6    E7   bye
(A I) (B J) (C K) (D L) (E M) (F N) (G O)  H
(H A) (M N) (L J) (C F) (O K) (B G) (D E)  I
(E F) (H B) (N O) (M K) (D G) (I L) (C A)  J
(D B) (F G) (H C) (O I) (N L) (E A) (J M)  K
(K N) (E C) (G A) (H D) (I J) (O M) (F B)  L
(G C) (L O) (F D) (A B) (H E) (J K) (I N)  M
(J O) (A D) (M I) (G E) (B C) (H F) (K L)  N
(L M) (K I) (B E) (N J) (A F) (C D) (H G)  O

Where the 15 teams are A to O, and where teams A to G have 8 games each (and play one event twice), and teams H to O have 7 games each.

Thank you. 

One more option... what would it look like if I only had 5 events?

Just assign the teams in columns E6 and E7 to be extra byes.
