Excel: How to concatenate another cell value in tab name for a formula

Hi guys

I have tabs for Game1, Game2, Game3, ..., Game99.

I have a 'Totals' tab with column A that is 1, 2, 3, ...

Question:  For columns B onward, what's the syntax for a formula if I wanted to grab  (i.e. replace <whatever number value is in XX of current tab> with ???)

=Game<whatever number value is in A1 of current tab>!$B$1
=Game<whatever number value is in A2 of current tab>!$B$4
=Game<whatever number value is in A3 of current tab>!$B$7

Thanks.
Jim
