Item 1.	Security and Issuer.  
  
	This statement relates to shares of the Common Stock, $0.00  
par value (the "Shares") of Aztar Corporation, a Delaware  
corporation (the "Company").  The principal executive offices of  
the Company are located at 2390 East Camelback Road,  Suite 400,

Item 2.	Identity and Background.  
  
	Item 2 is amended as follows:  
  
	This statement is being filed by FMR Corp., a Massachusetts  
Corporation ("FMR").  FMR is a holding company one of whose  
principal assets is the capital stock of a wholly-owned  
subsidiary, Fidelity Management & Research Company ("Fidelity"),  
which is also a Massachusetts corporation.  Fidelity is an  
investment advisor which is registered under Section 203 of the  
Investment Advisors Act of 1940 and which provides investment  
advisory services to more than 30 investment companies which are  
registered under Section 8 of the Investment Company Act of 1940  
and serves as investment advisor to certain other funds which are  
generally offered to limited groups of investors (the "Fidelity  
Funds").  Fidelity Management Trust Company ("FMTC"), a wholly- 
owned subsidiary of FMR Corp. and a bank as defined in Section  
3(a)(6) of the Securities Exchange Act of 1934, serves as trustee  
or managing agent for various private investment accounts,  
primarily employee benefit plans and serves as investment adviser  
to certain other funds which are generally offered to limited  
groups of investors (the "Accounts").  Various directly or  
indirectly held subsidiaries of FMR are also engaged in  
investment management, venture capital asset management,  
securities brokerage, transfer and shareholder servicing and real  
estate development.  The principal offices of FMR, Fidelity, and  
FMTC are located at 82 Devonshire Street, Boston, Massachusetts  
02109.  
  
	Members of the Edward C. Johnson 3d family are the  
predominant owners of Class B shares of common stock of FMR  
representing approximately 49% of the voting power of FMR.  Mr.  
Johnson 3d owns 12.0% and Abigail Johnson owns 24.5% of the  
aggregate outstanding voting stock of FMR.  Mr. Johnson 3d is the  
Chairman of FMR.  The Johnson family group and all other Class B  
shareholders have entered into a shareholders' voting agreement  
under which all Class B shares will be voted in accordance with  
the majority vote of Class B shares.  Accordingly, through their  
ownership of voting common stock and the execution of the  
shareholders' voting agreement, members of the Johnson family may  
be deemed, under the Investment Company Act of 1940, to form a  
controlling group with respect to FMR.  The business address and  
principal occupation of Mr. Johnson 3d is set forth in Schedule A  
hereto.  
  
	The Shares to which this statement relates are owned  
directly by six of the Fidelity Funds, and two of the Accounts.   
  
	The name, residence or business address, principal  
occupation or employment and citizenship of each of the executive  
officers and directors of FMR are set forth in Schedule A hereto.  
  
	Within the past five years, none of the persons named in  
this Item 2 or listed on Schedule A has been convicted in any  
criminal proceeding (excluding traffic violations or similar  
misdemeanors) or has been a party to any civil proceeding and as  
a result thereof was or is subject to any judgment, decree or  
final order enjoining future violations of, or prohibiting or  
mandating activities subject to federal or state securities laws  
or finding any violations with respect to such laws.  
  
  
  
Item 3.	Source and Amount of Funds or Other Consideration.  
  
	Item 3 is amended as follows:  
  
	The Fidelity Funds which own or owned Shares purchased in  
the aggregate 4,527,000 Shares for cash in the amount of  
approximately $33,478,821, including brokerage commissions.   
Except as described below, the Fidelity Funds used their own  
assets in making such purchase and no part of the purchase price  
is represented by borrowed funds.  Of the 617,200 Shares owned by  
one of the Fidelity Funds as of January 12, 1996, 617,200 Shares  
were purchased on margin pursuant to a typical customer margin  
agreement with Bear, Stearns & Co.  Proceeds from 1,636,200  
Shares sold aggregated approximately $13,999,175.  The attached  
Schedule B sets forth Shares purchased and/or sold since November  
13, 1995.  
  
	The Accounts of FMTC which own or owned Shares purchased in  
the aggregate 917,700 Shares for cash in the amount of  
approximately $7,664,471, including brokerage commissions.   
Except as described below, the Accounts used their own assets in  
making such purchase and no part of the purchase price is  
represented by borrowed funds.  Of the 200,100 Shares of common

Item 4.	Purpose of Transaction.  
  
	Item 4 is amended as follows:  
  
	The purpose of Fidelity and FMTC in having the Fidelity  
Funds and the Accounts purchase Shares is to acquire an equity  
interest in the Company in pursuit of specified investment  
objectives established by the Board of Trustees of the Fidelity  
Funds and by the investors in the Accounts.  
  
	Fidelity and FMTC, respectively, may continue to have the  
Fidelity Funds and the Accounts purchase Shares subject to a  
number of factors, including, among others, the availability of  
Shares of sale at what they consider to be reasonable prices and  
other investment opportunities that may be available to the  
Fidelity Funds and Accounts.  
  
	Fidelity and FMTC, respectively, intend to review  
continuously the equity position of the Fidelity Funds and  
Accounts in the Company.  Depending upon future evaluations of  
the business prospects of the Company and upon other  
developments, including, but not limited to, general economic and  
business conditions and money market and stock market conditions,  
Fidelity may determine to cease making additional purchases of  
Shares or to increase or decrease the equity interest in the  
Company by acquiring additional Shares, or by disposing of all or  
a portion of the Shares.  
  
	Neither Fidelity nor FMTC has any present plan or proposal  
which relates to or would result in (i) an extraordinary

liquidation, or sale of transfer of a material amount of assets  
involving the Company or any of its subsidiaries, (ii) any change  
in the Company's present Board of Directors or management, (iii)  
any material changes in the Company's present capitalization or  
dividend policy or any other material change in the Company's  
business or corporate structure, (iv) any change in the Company's  
charter or by-laws, or (v) the Company's common stock becoming  
eligible for termination of its registration pursuant to Section
