How Satoshi's Secret works

This is a six-reel slot with two bonus games. Note that the studio lists its RTP at 89.83%, well below the rest of the library. The Password symbol is the Wild.

Trading Bonus Game

Four Lock Bonus symbols scattered on reels 2, 3, 4 and 5 trigger the Trading game, which gives you starting capital. You decide whether to keep the win or risk it on a foreign exchange market for a chance to multiply it.

QWERTY Bonus Game

Getting QWERTY on the reels starts the hacking game. There are 3 levels of account protection with different amounts of money, and to leave safely you convert the money into cryptocurrency.

What to look for in the demo

Both bonuses ask you to decide when to stop. The demo is the place to learn what each choice costs.
