The daily login bonus seems to be fine, but should rather be something like "daily activity bonus" which means, that you need to be online for a specific time (like 60 or 120 minutes) a day, to keep the players active and reward them with little things. And the reward should increase in a daily row or just be completly random (not choosen rewards for everyday, because player who only need money, would login only at monday and thursday).

gem hunt sounds like a better option.
