Samoa provided group favourites England and South Africa with food for thought after opening their own campaign with a comprehensive victory over Uruguay.
John Boe's side, the last to show their wares at this tournament, provided plenty of invention and incisive running to rattle up 10 tries at Perth's Subiaco Oval.
Impressive flanker Maurie Fa'asavalu and veteran centre Brian Lima led the way with first-half braces as Samoa secured a bonus point inside half an hour.
Uruguay earned some consolation in scoring their first tries of this World Cup, number eight Rodrigo Capo and prop Pablo Lemoine rewarded for another committed forward effort.
But Samoa appeared capable of scoring each time they found space to run, Lome Fa'atau scoring the pick of the tries with a sublime side-stepping effort early in the second half.
The wing blotted his copybook with a yellow card for a blatant bodycheck on Uruguay scrum-half Juan Campomar late on, but it came too late to affect the outcome.
Samoa had to wait until the 12th minute to open their account, but once Fa'asavalu showed devastating pace to score from inside his own half, the floodgates swiftly opened.
Neat interplay down the right flank brought a second as lock Opeta Palepoi flicked the ball out of the tackle for Lima, playing in his fourth World Cup, to touch down.
Fly-half Earl Va'a missed both conversions, but was on the mark after 24 minutes when wing Sailosi Tagicakibau exposed hesitation in the Uruguayan defence to collect the stand-off's high kick and race away for the third.
Palepoi was a powerful presence
A flowing move produced a second try for the rampaging Fa'asavalu, bringing up the bonus point for Samoa in the 28th minute.
Then Lima, showing impressive pace, stepped off his left foot and surged away for the fifth, Va'a converting for a 29-0 lead.
Uruguay did stem the tide before the interval, Capo snaffling a loose ball from a scrum close to the Samoan line to touch down in the left corner.
The number eight celebrated with aplomb, but it was to prove a brief respite.
A surge from captain Semo Setiti created space for Fa'atau's weaving effort on the resumption before replacement prop Simon Lemalu charged over from the back of a maul.
Vili pounced on a fumble from Uruguay full-back Juan Ramon Menchaca to grab the eighth by the 54th minute, but the South Americans refused to capitulate.
Former Bristol prop Lemoine was driven over for a popular score, and Uruguay spent much of the last quarter in Samoa territory.
But the Pacific Islanders finished with a flourish, replacement Dominic Feaunati and Palepoi adding further scores in the closing minutes.
