A couple weeks ago my 11 year old daughter beat me in this in a typical last-minute cliff-hanger game.
The game is so unpredictable - all the chances are 50% die rolls or coin tosses - it is ideal for solitaire play too.
8 half-month turns for U.S. or Japan to take and keep Henderson Field, Guadalcanal.
2 battleship, 2 cruiser - a 3rd for U.S. if/when 1 is lost - 2 carrier, and 2 transport pieces each, plus Yamato for Japanese if an IJN battleship piece is lost.
6 ground units each
5 U.S. and 4 Japanese air units.
Codebreaking, night combat, radar, Torpedo Junction, Long Lance torpedoes for Japanese cruisers with Night surprise.
And anyone is free to print this or my other 3 (so far) postcard games off in postcard format ... as long as my copyright statement and the Dedication are retained ... to mail/give to family and friends.
(Of course, for your own personal copy you will want to photocopy-enlarge the components ... the front at both A4 (for the units) and A3 (for the chart) and the back/rules as large as you need them. :-) )
