I find they work many different avenues to get you to purchase frequently and all too infrequently award you reasonable points so as to not have to spend hundreds and hundreds often thousands and thousands to continue to play at any reasonable rate or frequency. I have been playing this game for quite some time and have had only one chest to still find, and yet more than a month has gone by and I have not gotten that last chest, which would give me $1 billion bonus. In some of the special items like the cosmic collection or whatever they’re called each time where you can end up with a grand prize, after getting many chests all the news etc. Hearts of Vegas has many many games, giving people options which is good although there are much too many and I end up playing only 2 to 3 on average.
