It can be easily viewed as a low quality game, but you should not judge it through its cover. The game also comes with a free demo mode that you can try on yourself without paying for it.
In addition to the jackpot, the free spin of Wu Hao Cai Wei has three free spins caused by the wind chimes. One confusing aspect of free spins is that Playtech advertises them as "unlimited", but it's impossible to re-trigger free spins, so we're not sure what makes them unlimited.
