           NEW YORK, May 4, 2005 - Six Flags, Inc. (NYSE: PKS) announced today
its results of operations for the quarter ended March 31, 2005.

           Revenues for the 2005 quarter were $54.4 million, representing a
21.3% increase from the 2004 quarter. The increase reflects an attendance
increase of 330,000, or 25.1%, resulting from a positive market reaction to our
new capital additions, especially in our Mexico City park, as well as the
greater number of operating days due to the timing of the Easter holiday.
Revenue per capita declined by 3.0% for the quarter, reflecting primarily the
larger percentage of operations in the quarter from our Mexico City park, which
has lower per capita revenues than our domestic operations. This is expected to
reverse as we move into our key domestic operating season.

           Operating costs and expenses, including depreciation and amortization
and non-cash compensation, were $171.5 million in the first quarter of 2005, as
compared to $162.0 million in the 2004 quarter, an increase of 5.8%. Excluding
depreciation and amortization and non-cash compensation, cash operating costs
and expenses were $133.7 million in 2005, as compared to $124.9 million for
2004, an increase of $8.8 million (7.0%). This increase includes $1.3 million in
increased costs of goods sold primarily reflecting higher in-park revenues. It
also includes other planned increases in operating expenses reflecting the
earlier commencement of park operations in many markets due to the timing of the
Easter holiday.

           EBITDA (Modified) was ($79.3) million in the first quarter of 2005 as
compared to ($80.1) million in the 2004 quarter. Adjusted EBITDA, which excludes
the interests of third parties in EBITDA from our non-wholly owned parks, was
($74.0) million in the 2005 quarter, as compared to ($74.1) million in the 2004
quarter. (1)

           The loss from continuing operations in the 2005 quarter was $178.7
million. The loss reflects the recognition of an additional valuation allowance
of $67.2 million recorded in 2005 with respect to the Company's domestic
deferred tax asset, solely as a result of off-season losses. This has the effect
of increasing book tax expense for the period by the amount of the allowance.
This has no effect on the Company's cash tax expense or its ability to utilize
net operating loss carry forwards in future profitable years. Absent this
valuation allowance, the loss from continuing operations would have been $111.5
million in the 2005 quarter, as compared to $119.9 million in 2004.

DISCUSSION AND OUTLOOK
- ----------------------

           Kieran E. Burke, Chairman and Chief Executive Officer of Six Flags,
said, "We are pleased with the start of our 2005 season.

           "We have seen good performance in the aggregate at our parks that are
currently in operation, although operations in the first quarter and year to
date are not meaningful portions of our full year. Attendance year to date
through last Sunday is 4.2% ahead of the prior year and park level revenues are
up by 3.3% year over year. Further, we continue to experience growth in hard
ticket group bookings and are substantially ahead in season pass sales.

           "We expect attendance growth in 2005 to be driven by our robust plan
for capital additions to our parks combined with our ongoing guest service
initiatives. That plan encompasses new attractions in 13 of our 18 domestic
theme parks and three of our water parks, and a children's area in our Montreal
park, with the largest initiatives concentrated in our major markets, especially
in Chicago and New Jersey. We have also added a major new roller coaster in our
park in Mexico City which continues to experience strong year over year
attendance gains. We believe that this investment program should drive
significant attendance and revenue growth in 2005 and set the stage for several
years of significant growth.

           "We continue to anticipate generating Adjusted EBITDA of $300 million
in 2005. This is based on expected attendance growth of approximately 4.75% and
a per capita spending increase of approximately 2.5%."

(1)  Revenues and expenses of international operations are converted into
     dollars on a current basis as provided by accounting principles generally
     accepted in the United States ("GAAP").

(2)  The Company's reported results include items of income and expense that we
     believe are typically excluded by securities analysts in their published
     estimates for the Company's financial results. These excluded items include
     gains and losses on early repurchases of debt and deferred tax asset
     valuation allowances. The following tables set forth the calculation of net
     loss applicable to common stock and net loss applicable to common stock per
     common share (basic) before giving effect to those excluded items and
     before discontinued operation, in the case of the 2004 period. This measure
     is not defined by GAAP and should not be considered in isolation or as an
     alternative to net income (loss), income (loss) from continuing operations,
     net cash provided by (used in) operating, investing and financing
     activities or other financial data prepared in accordance with GAAP or as
     an indicator of the Company's operating performance.

(3) EBITDA (Modified) is defined as net loss before discontinued operations,
income tax expense (benefit), other expense, early repurchase of debt (formerly
extraordinary loss), minority interest in earnings (losses), interest expense
(net), non-cash compensation, amortization and depreciation. Adjusted EBITDA is
defined as EBITDA (Modified) minus the interest of third parties in EBITDA of
the four parks that are less than wholly owned. The Company believes that EBITDA
(Modified) and Adjusted EBITDA (collectively, the "EBITDA-Based Measures")
provide useful information to investors regarding the Company's operating
performance and its capacity to incur and service debt and fund capital
expenditures. The Company believes that the EBITDA-Based Measures are used by
many investors, equity analysts and rating agencies as a measure of performance.
In addition, Adjusted EBITDA is approximately equal to "Consolidated Cash Flow"
as defined in the indentures relating to the Company's senior notes. Neither of
the EBITDA-Based Measures is defined by GAAP and neither should be considered in
isolation or as an alternative to net income (loss), income (loss) from
continuing operations, net cash provided by (used in) operating, investing and
financing activities or other financial data prepared in accordance with GAAP or
as an indicator of the Company's operating performance.

           The Company is not able as of this date to provide a reliable
estimate of its income tax benefit and other income (expense) for the year
ending December 31, 2005. Therefore, a reliable estimate of its net loss for
that year is not available. Accordingly, the following table sets forth a
reconciliation of expected income from operations for 2005 to expected EBITDA
(Modified) and expected Adjusted EBITDA for such year. Since the EBITDA-Based
Measures are calculated before income taxes and other expense, the absence of
estimates with respect to these items would not affect the expected EBITDA-Based
Measures presented. For 2005, expected interest expense (net) is approximately
$185,000,000 and expected minority interest in earnings is approximately
$39,000,000.
