Kronos is a slot game that begs to differ from the others. When it comes to absolute simplicity, you can't go wrong here. The lines that can be covered only contain 20 in total. Stakes are sensible enough when starting at a penny up through a 3 dollar limit per line.
The top paying symbol which is the image of old Kronos himself, doesn't do anything except payout wins for each that lands on the paylines. His top award is 2,250x the stake for 5 symbols in a payline. The wild is a sculptured lion which only shows-up on the 2nd, 3rd, and 4th reels.
Various playing card symbols can do flip-flop subs for each other, while the scatter logo (which looks like a fan blade) awards the free spins. With 3 or more of these you may have 10, 25, or 100 spins in the order of 3, 4, and 5, scatter symbols anywhere on the reels. As expected there is a jackpot bonus that may be triggered at any time whereas the gamble game Double-Up may be set to appear on any win desired.
