There are four levels to be solved.
-The first level Hummingbird - 1match to move
-The second level Mockinbird - 2 matches to move
-The third level Falcon - 3 matches to move
-The fourth level Hawk - 4 matches to move
On each level one move equals one point. If a player uses a hint one point is lost. The hints are available from the second level.
To move to the next level a player has to solve certain number of equations starting from the Hummingbird level, for example the Hummingbird level - 300 simple equtions. On each level it it possible to choose the other/next eqation by clicking Next. It is also possible to come back to the previous move.
The Multiplayer option is the game for two players - it is a simpler version of the game. The multiplayer mode works only in the same WIFI network.
