Gamifying the exploration of a lesser known part of Singapore was exactly what that area needed to be done justice! I really loved how the balance was achieved between the difficulty of riddles and the itinerary indications, which gave way to a very carefully crafted pathway, full of teachable moments and unexpected discoveries -and I did half of it under tropical rain: did not discourage me for a bit. One might argue that one or two riddles were a bit tortuous to guess, and I think one of them did not accept my right answer, which led me to losing points ;) But all in all, the experience was fantastic, and thanks to the gaming and adventure component, I retained information much better than if I had been a passive tourist in a traditional tour. I vividly recommend this game -and the use of that app in general.
