How to show a View with Rules
Assume that the path to the view you want to show is "SomePath". Then just create a rule with a Rules Action to "perform a redirect", to the path SomePath.

For a rule with such Rules Action, you just use whatever Rules Event that fits your needs (something related to user points I assume), and optionally add whatever Rules Conditions that fit. For a rule that you can probably use as a good starting point, have a look at my answer to "How to change user info with a rule when Points are granted to user (using userpoints module)?" (if you'd just add a Rules Action to redirect, you may be close already).
