Start with slots, not games
Draw a grid: one column per field, one row per time slot. A slo-pitch game usually takes a 60 to 75 minute slot. Every cell is one game you can play. Count the cells before you count the games.
Give teams rest
No team should play two slots in a row unless you have no choice, and none should sit out half the day between games. A gap of one slot between games is the comfortable middle.
Spread the early and late games around. If one team has the 8 am game on both days, you will hear about it.
Keep teams near one field
On a complex where diamonds are far apart, keep each team on the same field or the fields next to each other for back-to-back games. Moving gear across a park eats into the gap you gave them.
Leave a buffer
Games run long. Leave one empty slot somewhere in the middle of the day on at least one field. It soaks up delays without pushing every later game back.
Publish one link, not a picture
Schedules change. A photo of a spreadsheet in a group chat cannot be corrected, and the wrong version lives on. Publish one link that always shows the current schedule, and let each team find its own games.
