Changing MOVEMENT is one of the dynamic features of the game. The piece is represented by the triangle on it's grid, and it may move to ANY YELLOW-SQUARE on it's grid. YELLOW-SQUARE movement is UN-BLOCKABLE.
Some pieces attain unlimited ARROW movement which IS blockable. Dotted Arrowed movement allows your piece to IGNORE the first intervening piece as if it were not there. Some pieces are able to SACRIFICE themselves in order to attain a special affect.
The game is 'pronounced' as "Naaviah Draap" (without the t). People pronounce dratp many ways: rhymes with 1- tap, rap, map. 2- top, mop, pop. 3 tape, gape, grape. BUT if you want to pronounce it as the Japanese which sounds much cooler, try this: Navuia Dorappu (Nah-vwee-ah Doe-rah-poo) or just from the official instructions: (nah-vee-ah drap)
As an ABSTRACT game, both sides know all the powers of the pieces.
