From Emanuele Feronato: "Recently I played o:anquan on my iPhone, published by Pine Entertainment. The idea behind o:anquan is inspired by the control of a traditional Vietnamese children’s board game.
You play on a 6×6 board, and each turn three random numbers between 1 and 9 are placed in three random empty spots on the board. The player at this time can select a number and drag it around the board, only passing across empty spots. At each step, the number decreases and leaves a “1” behind it. At the end of the turn, all matching numbers are removed from the board, and three new numbers appear. The game ends when there aren’t possible moves.
It’s really easier to play than to explain, so have a go, since it’s free.
The game engine is a simplified version of Globez, the same engine I used in the making of Dungeon Raid tutorial series and in the making of DrawSum HTML5 game which I also ported as a free Google Play Android game, which I invite you to donwload and play as well as read the “making of”."
