Enter a game without going into the page ?

Pretty sure I saw a script out there not too long ago that adds a enter giveaway button to the browsing page, searching the discussions for scripts may bring up what you are looking for.

yes, it's an awesome idea to ignore giveaway descriptions.
totally respectful towards ga creators since they are only here to give us free games. 💖

Clicking to enter a giveaway must be a real chore then. ;_;

There are many auto-join scripts, but I would have to recommend against using them. If you want, you could just middle-click the GA and open them in separate tabs, then just join from there.

It won't be officially added; since every giveaway page loads another ad, thus generates revenue for SG.

Group giveaway, private giveaway, invite only giveaway requires you to read the description cause it contains further info such as ( rules in group giveaway case) or even better, more giveaway link attached to it. So ignoring em is not recommended.
