                                  CERTIFICATION

I, W. Bruce Turner,  President  and Chief  Executive  Officer of GTECH  Holdings
Corporation (the "Company"), certify that:

(1)       I have reviewed this amended report on Form 10-Q/A of the Company;

(2)       Based on my knowledge, this amended report does not contain any untrue
          statement  of a  material  fact  or  omit to  state  a  material  fact
          necessary to make the statements  made, in light of the  circumstances
          under which such  statements were made, not misleading with respect to
          the period covered by this amended report;

(3)       Based on my knowledge,  the financial statements,  and other financial
          information  included in this amended  report,  fairly  present in all
          material respects the financial  condition,  results of operations and
          cash flows of the  Company as of, and for,  the periods  presented  in
          this amended report;

(4)       The  Company's  other  certifying  officer and I are  responsible  for
          establishing  and maintaining  disclosure  controls and procedures (as
          defined  in  Exchange  Act Rules 13a - 15(e) and 15d - 15(e))  for the
          Company and we have:

          (a)     designed such disclosure  controls and  procedures,  or caused
                  such  disclosure  controls and procedures to be designed under
                  our supervision,  to ensure that material information relating
                  to the Company,  including its consolidated  subsidiaries,  is
                  made known to us by others within those entities, particularly
                  during  the  period in which  this  amended  report  was being
                  prepared;

          (b)     evaluated  the  effectiveness  of  the  Company's   disclosure
                  controls and  procedures  and presented in this amended report
                  our  conclusions  about the  effectiveness  of the  disclosure
                  controls and  procedures,  as of the end of the period covered
                  by this amended report based on such evaluation; and

          (c)     disclosed in this amended  report any change in the  Company's
                  internal  control  over  financial  reporting  (as  defined in
                  Exchange  Act Rules  13-15(f)  and  15d-15(f))  that  occurred
                  during the  Company's  most  recent  fiscal  quarter  that has
                  materially  affected,  or is  reasonably  likely to materially
                  affect,   the  Company's   internal   control  over  financial
                  reporting; and

(5)       The Company's other certifying officer and I have disclosed,  based on
          our  most  recent  evaluation,  of  internal  control  over  financial
          reporting,  to the Company's  auditors and the audit  committee of the
          Company's board of directors:

          (a)     all significant  deficiencies  and material  weaknesses in the
                  design  or  operation  of  internal   control  over  financial
                  reporting which are reasonably  likely to adversely affect the
                  Company's  ability to record,  process,  summarize  and report
                  financial information; and

          (b)     any fraud,  whether or not material,  that involves management
                  or  other  employees  who  have  a  significant  role  in  the
                  Company's internal control over financial reporting.
