Rather mediocre gameplay which becomes terribly repetitive after just the first few levels. Great game for in bed or on the toilet, otherwise not very substantial and just existing to take your money. Offline turn regen works when the game feels like it, again coaxing and coercing you into buying moves or using scam advertisements to gain turns.
Avoid as the plague if you are easily distracted by advertisements, unless you like leaving your PayPal and credit card with the nearest Russian you come across.
