Active PUZZLE; it is a mini-event in which by playing up to 114 games in a span of 3 days you can claim lucky spins with the possibility of getting miners among other rewards for your room, for free. Every Tuesday there are also lucky rlt cases that can be opened and extra spins can be claimed apart from those from the games. The rlt is obtained by depositing and making a crypto/rlt exchange or by playing mini-games where you can drop up to 1rlt, achievements, etc.
With 30rlts I opened the 72 boxes of 1.45rlts, I made a profit +10 for next Tuesday or to spend on miners.
