If the symbols are not identical, click the 'no' button. In the beginning of ervery block you will receive the processing rule. This tells you, which of the recently seen symbols you have to compare with the current symbol. For example: 2-back means you have to compare the current symbol with the one before the last one. At 3-back it would be the symbol three symbols before, at 4-back the symbol four symbols before etc. Please note: Symbols are identical if they matche in both shape and colour.
