If you are not careful as hell, it may even happen that you accidentally clicked something and buys. Happened to me - and whoosh, I had the same armor twice, paid for fortunately only with free aufgesammeltem play money. After each round new Ausrüstungsgengenstände offered, it would be nice if the random number generator could remember what already exists. To protect any case the real purse from accidental in-app purchases, I use the child lock in the shop. As always in these games so should people who can not control himself, better leave it alone.
But who has his shopping behavior under control, can this mix of match 3 and turn-based RPG abgewinnen lot. I, for example, although the purse, but not the clock under control and already spent hours. The challenge and excitement is like here already someone wrote to move forward without any real money. Of course, it costs a little patience. One has to wait (after 20 days, there is a valuable armor or weapon, for example, the aforementioned expensive Ice Sword choice!), Or to improve play money supply and health, sometimes to simpler levels decline (although due to increasingly stronger opponents also there is not without problems, so always prefer to cancel a fight before as all health points to lose). But all worth it, at some point so you can get the paid extras too. I've invested a single penny in the game and this is also not available.
Other strategic tips: The Rune mt healing function (+) is a must and should be bought early. It is easy to recharge with water used anyway symbols and thus utilize quite incidentally. If later a silver Heilungsrune appears in the shop, you should switch to this, it acts much more. Otherwise: Not all equipment that one or two steps brings improvement, must be purchased the same, the future resale value is low. Better save the same on something expensive. The same is true for unlocking runes places, which should be done with consideration, because with new equipment new unlocks must often be purchased again and skillful players do not need all the seats. But if after all what is still free, you can usefully use the stones, which strengthen attack and defense.
So far, I am quite done well with this strategy, halfway through, but that does not matter, Rome was not built in a day and there are other exciting apps. For a truly addictive gameplay and nice graphical display there are just four star. The rip-off would have but really not. I would have paid for the game itself quite a few euros, but selling stupid I do not like to let myself. So only recommended for people with self-control and child lock to prevent accidental purchases.
