### Test 1: When the players change ends

- Ends change after games 1, 3, 5 and so on. (Source: ITF Rules of Tennis 2026, Rule 10)
- Nine games is an odd total, so they change as the set ends. (Source: ITF Rules of Tennis 2026, Rule 10)
- Ten games is an even total, so the change waits one game. (Source: ITF Rules of Tennis 2026, Rule 10)
- In a standard tie-break they switch each time six more points have been played. (Source: ITF Rules of Tennis 2026, Rule 10)
- The alternative switches ends sooner and more often. (Source: ITF Rules of Tennis 2026, Appendix VI (Change of ends))
- The tie-break counts as one game, making 13. (Source: ITF Rules of Tennis 2026, Rule 10)
- Three games is odd, so ends change. (Source: ITF Rules of Tennis 2026, Rule 10)
- Players stay put for the opening game of the next set, then switch. (Source: ITF Rules of Tennis 2026, Rule 10)
- One point, then every four. (Source: ITF Rules of Tennis 2026, Appendix VI (Change of ends))
- Ends change after odd-numbered games only, and four is even. (Source: ITF Rules of Tennis 2026, Rule 10)
