The Bank of Canada is up to its old tricks again.
A video game dubbed ``Inflation Busters'' has been hidden on the Bank's website promoting the country's new 10-dollar bill featuring civil rights figure Viola Desmond.
To unlock the game -- which is similar to the classic arcade game ``Space Invaders'' -- visitors to the website must repeatedly click a ``spin'' button.
The central bank also added a so-called Easter egg to its website last spring when it unveiled the design for its 10-dollar bank-note to celebrate the 150th anniversary of Confederation.
