For example, the mechanical reels of traditional gaming machines have been replaced with video depictions of spinning reels. These video gaming machines provide a richer gaming experience for players by including graphics or animation as part of the game. However, overly complex video displays on a gaming machine may turn off player participation because players become frustrated with the game or are unwilling to learn or decipher all the information provided on the video display. Accordingly, there is a continuing need for slot machines variants that provide a player with enhanced excitement without departing from the original slot machine gaming concept. Asphalt is a common material utilized for the preparation of paving and roofing materials and also for coatings such as pipe coatings and tank liners. While the material is suitable in many respects, it inherently is deficient in some physical properties which it would be highly desirable to improve. Efforts have been made in this direction by addition of certain conjugated diene rubbers, ethylene containing plastics like EVA and polyethylene, neoprene, resins, frillers and other materials for the modification of one or more of the physical properties of the asphalt. Each of these added materials modifies the asphalt in one respect or another but certain deficiencies can be noted in all modifiers proposed. For example, some of them have excellent weather resistance, sealing and bonding properties but are often deficient with respect to warm tack, modulus, hardness and other physical properties; and some of them improve only the high temperature performance- of asphalt, some only improve the low temperature performance of asphalt, while some lack thermal stability or mixing stability with asphalt.
Since the late 1960s, diene polymer rubbers such as styrene-butadiene rubber and styrene-rubber block copolymers such as styrene-butadiene-styrene and styrene-isoprene-styrene block copolymers have been used to dramatically improve the thermal and mechanical properties of asphalts. Practical application of the rubber addition approach requires that the blended product retain improved properties and homogeneity during transportation, storage and processing. Long term performance of elastomer-modified asphalts also depends on the ability of the blend to maintain thermal and chemical stability.
To be suitable for paving materials, the asphalt polymer mixtures should meet the following requirements:
(a) The polymer must be mixable in asphalt and stay mixed during subsequent processing--compatibility. In a modified asphalt composition, compatibility is important. The polar

Asphalt is a common material utilized for the preparation of pave and roofing material and also for application such as organ pipe application and tank liners. While the fabric is suitable in many deference, it inherently is deficient in some physical property which it would be highly desirable to improve. Efforts have been made in this direction by summation of certain conjugated diene rubbers, ethylene containing plastic like EVA and polyethylene, neoprene, resins, frillers and early material for the modification of one or more of the physical properties of the asphalt. Each of these added materials modifies the asphalt in one respect or another but sealed deficiencies can be notice in all modifiers proposed. For exercise, some of them have excellent weather immunity, sealing and bonding property but are often insufficient with respect to warm tack, modulus, hardness and early physical properties; and some of them improve entirely the high temperature performance- of asphalt, some entirely improve the low temperature performance of asphalt, while some lack thermal stability or mixing stability with asphalt. 
 Since the late 1960s, diene polymer rubber such as styrene - butadiene rubber and styrene - rubber pulley copolymers such as styrene - butadiene - styrene and styrene - isoprene - styrene block copolymers have been used to dramatically improve the thermal and mechanical properties of asphalt.
