So constructive suggestions on this event:
1- Basically what you did, with another design, was simply replacing the different chests with different prizes for a single chest with very bad prizes, rubbish for the most part like 2x1 culture buildings (i got 2 of those), runes, spells and relics that make the majority of the prizes. If we can't choose what prizes we want to spend our ribbons at least put some decent prizes in the lot;
2- Before we could get 2x2h time instants in the 18 thingies chest and 4x8h in the 82 chest with decent probabilities. Now, for 60 thingies, i saw, never got, just absolute rubbish so far, 1x1h and 1x2h with probabilities 2/16 for both. So far, before shuffling, I saw at least 12/16 or 75% probability of getting absolute garbage, 1/16 of getting the daily and 3/16 of not complete rubbish (but not good, there is never a good prize in the lot). If we really want a daily and are unlucky not too have the reshuffle one we have to spend 16x60 ribbons to get again a minute chance of winning it. So add a reshuffle button that we can hit as soon as we open one present if we don't like what we see or really want the daily;
3- Before we had chests of 18 up to 142 thingies giving 1,2,3 or 5 stars or whatever. Now we just have 1 hammer per 60 ribbons. The casino thing with the hammer is completely unnecessary, but it you insist, assuming the odds are even that's 2 bricks average per hammer so 1 brick per 30 ribbons way above the more expensive chest in the previous format. So you need to lower the amount of ribbons per shot comparable with what we had on average on the old format
