Since the re-regulation of the market, operators with a Swedish license may only offer customers bonuses at the first game opportunity.
The Gaming Inspectorate has found AG Communications and Genesis brached this law, fining the companies SEK 500,000 ($52,000) and SEK 1.7m respectively.
According to gaming legislation, an offer of more than one bonus is sufficient for the license holder to have violated the clause.
AG communications provides games on a selection of websites including karamba.com, mrplay.com, spinson.com and vikingslots.com.
Genesis also has a long list of websites it provides games for, including genesiscasino.com, vegashero.com and casinogods.com.
This is Genesis’ second fine in the new Swedish market. It first received an official warning and levy of SEK 4m for self-exclusion failings on 22 March.
Operator Paf was this year hit with a self-exclusion-related fine, to the amount of SEK 100,000.
The sanctions relate to the companies’ failure to join the mandatory self-exclusion register Spelpaus.se.
