                    [CCTransitionRadialCW transitionWithDuration:1.0f scene:[newSceneName scene]]];

        // For Transition shrink grow
            [[CCDirector sharedDirector] replaceScene:
                    [CCTransitionShrinkGrow transitionWithDuration:1.0f scene:[newSceneName scene]]];

        // For Transition split rows
            [[CCDirector sharedDirector] replaceScene:
                    [CCTransitionSplitRows transitionWithDuration:1.0f scene:[newSceneName scene]]];

        // For Transition turn off tiles
            [[CCDirector sharedDirector] replaceScene:
                    [CCTransitionTurnOffTiles transitionWithDuration:1.0f scene:[newSceneName scene] ]];

        // For Transition zoom and flipping X with orientation
            [[CCDirector sharedDirector] replaceScene:
                    [CCTransitionZoomFlipX transitionWithDuration:1.0f
                    scene:[newSceneName scene] orientation:kOrientationRightOver]];
