This game is similar to the "Spirit of the Glass", here in the Philippines. I played it together with friends twice. Everyone enjoyed it the first time. We have our fingers over the upturned glass so lightly. The glass tilted because it was spinning fast as it moved from letter to letter to answer our questions. How can it be? If the glass just moves towards the letters maybe we could accuse each one cheating by deliberately pushing the glass, but spinning fast? The glass even moved faster that we have to lean so that we can keep our fingers still on the glass.
We played it again the next day. After saying a prayer, the person who led the game asked: "Spirit, are you in?" After several minutes of waiting, the glass moved to the letters Y-E-S. Then she asked again, " 'Spirit' would like to play with us?" The glass moved to the letter 'N' then to the letter 'O'. When she asked the spirit why he/she wouldn't play with us, the glass moved to the letters S-I-N. We're taken aback. After more silence, the leader asked if the spirit would like us to say a prayer for her/him, the glass moved to N-O. We never played that game again. Ever.
