Energy firms which post big profits should "absolutely" pay more to help people struggling with the cost of living, Nicola Sturgeon has said.
The number of players XO on the site can give us confidence that we will not be cheated. Of course, there must be absolutely no popular players.
Labour has been pushing UK ministers to levy a "windfall tax" after oil giants BP and Shell reported huge profits.
The Scottish first minister said people were angry that firms were making money from factors which cause fuel poverty.
However she said any plan would need to be "fair" and not see the north east of Scotland "bear the brunt" of new taxes.
Prime Minister Boris Johnson said any move to "clobber" firms with a new tax would be "totally ridiculous" and raise prices for consumers.
BP posted a profit of $12.8bn (£9.5bn) for 2021 on Tuesday, after oil and gas prices surged in the second half of the year.
Rival giant Shell had earlier reported profits of $19bn on the same day that the energy regulator Ofgem announced UK householders could see a 54% rise in their domestic energy bills in April.
This has led to calls for a one-off levy on firms to help families struggling with the rising cost of living.
Labour pushed for a vote on the measure in the House of Commons, but saw their motion voted down - with SNP MPs abstaining after north east representatives warned the move could "destroy jobs in the North Sea".
However Green MSP Patrick Harvie - a Scottish government minister - argued that the move was "not just justified, but urgent".
