I've been using clixgrid to effectively unlock the daily bonus.

If I've completed other tasks and offers and earnt $2, then by doing the clixgrid game I get an extra 5cents or so. Which 'pays' for the clixgrid at a slightly lower rate than normal adds.

That's how I've been looking at it.

But I don't think I would do it if there wasn't a daily bonus to unlock.
