Wales centre Scott Williams admits his side will be eager "to get as many points" as possible when they face Uruguay at the Millennium Stadium.
The hard-running Scarlets back, who knows the margin of their win could be crucial at the end of the pool, can't wait to get the ball rolling in Cardiff.
"It's an exciting time. Time has flown by and I think we're all ready to go now. Hopefully, the work we've done will pay off over the next few weeks," he said.
"It's going to be a massive occasion for Uruguay. To play in one of the best stadiums in the world is massive. However, they will be ready to go."
He added on their objective for Sunday: "To get as many points as we can. It will probably be like our final game of the Six Nations (when Wales needed to score as many points as possible against Italy to stand any chance of winning the championship). The most important thing is we put a performance in that gives us something to build on.
"We have to make sure we are on our game to get the performance we want. We have got to make sure we do the basics well and keep the errors down. Against Italy we made too many mistakes. If we cut them down over the next few weeks, I think we will be OK.
"Looking back at the Italian game, we left a couple of opportunities out there early on. If we had scored, it would have been a completely different game."
Not having defensive lapses will be just as important as running in the tries for Wales and Williams explained they will be pulled up on any error by the coaches in their post-match review.
"You don't want to be the name on the board on Monday morning for a defensive error. If you are, you're going to have Shaun (Edwards) on your back," he said.
"Shaun certainly isn't scared of embarrassing anyone, which is good because it keeps you on your toes. There will always be a Monday review which comprises a defence and a team review. There's a couple of comments on each player, on how we've played. If he's got a couple of video clips to show he will.
"All the other coaches – attack, set-piece and contact area – do the same; we get a lot of information given back to us.
"Everyone has been on the wall of shame. We are only human. Shaun wants to improve us and his way of helping us is by embarrassing us. It's on the TV so you can’t rub it out."
