What you want is not to register PlayerEqualizer instances as Transient but as Instance Per Dependency.

Technically, both lifestyles are the same, as they both return new instances on every request. The intend of Instance per Dependency is however, very different, because:

Each consumer will get a new instance of the given service type and that dependency is expected to get live as long as its consuming type.

While with Transient the intention is the dependency to be short-lived.

This lifestyle is deliberately left out of Simple Injector, because:

its usefulness is very limited compared to the Transient lifestyle. It ignores lifestyle mismatch checks and this can easily lead to errors, and it ignores the fact that application components should be immutable. In case a component is immutable, it’s very unlikely that each consumer requires its own instance of the injected dependency.

The project's Code Samples however contains the definition of a InstancePerDependencyLifestyle that does what you want it do do:

• It gives every consumer its own instance
• It ignores lifestyle mismatches on the registration, since the instance is expected to live as long as its consumer

You can use this lifestyle as follows:
