Game rules of the Grandma's Attic slot

In the free version of the slot, you are given credits to play. To simplify calculations while betting, credits are converted into coins. So, playing the one-armed bandit starts with the selection of the value of one coin in the range from 0.01 to 1 credit. Then the bet and the number of paylines are adjusted and a spin is launched.

The main buttons for managing the online slot are found on the panel below the reels:

  • Start — initiates one spin of reels
  • Auto — activates auto spins. But the mode with auto spins is only available in the full version of the slot
  • Bet Max — launches a spin of the reels with the highest bet per spin — 75 coins
  • Select Lines — chooses the number of active paylines from 1 to 15
  • Select Coins — sets a bet per line from 1 to 5 coins
  • The "-" and "+" buttons adjust the cost of a coin from 0.01 to 1 credit

Two View Paytable buttons are found at the top of the game window. They open a section with information about your winnings for combinations and about features of bonus symbols. The Back to Slot button closes the information table and returns you to the main game.

These windows enable you to monitor the game:

  1. Win — tells you the amount of the latest win

In this round, the multiplier x3 is applied, that is, all wins are tripled.
