You can only change the denomination of the coin in Yggdrasil Slots.
A full coin is equal to 20 euros. The win displayed must be split if your bet is less than one full coin. However, as in Netent Slots, there is a doubling area that always shows your winnings in real money, not coins.
The minimum bet is 0.2 (20 lines with a bet of 0.01 per line)
b. Adjustment of paylines is not possible.
