Below games are all of inland manufacture. They are however counted among MONOPOLY games, because properties have to be bought on which the owner can build and so increase his fortune.
Not until 2005 Hasbro introduced their Thai version..

Did you know the link to this chapter looks in Thai like this: เกมเศรษฐี ของไทย แบบต่างๆ ? 
This referrence is in the Thai Wikipedia chapter on Monopoly! Thank you for that.

Publisher: Leaping Dog - 1995?
Dimensions of the box: 22.7 x 39.8 cm
The game:
This edition is in every respect identical to the previous one, except for 2 points:

The game:
The board is of soft carton with a blue play side and a blue back. There are 29 numbered properties, who show national landmarks (?) on the board.

However the color is successively pink - red - yellow - light brown and again light brown. The property cards are white and mention the rent that is subject to the number of houses or number of properties. (Before they can be used they have to be torn loose of a sheet) It is striking that at the space of Electric Company (9) and Water Works (22) in this game is something similar!
In Jail is a "motocyclist" behind bars! By the way, you're not ORDERED to go to Jail, but on the contrary BROUGHT to in a little car! On the Free Parking space is now a Water power station.

Dimensions of the box: 22.4 x 37.6 cm
The game:
This set is identifiable by the 6 children at an Automatic Teller Machine on the cover.

The properties are spreaded over 5 color groups, but it is not clear how they go together. It appears from the property cards that the numbers 5 - 10 - 17 and 25 do NOT build up a group. Besides the color is successively purple - yellow - purple and yellow again. The property cards are white and mention the rent that is subject to the number of houses. (Before they can be used they have to be torn loose of a sheet)
Jail shows is a little man behind bars but there are boxes also, a.o. a first-aid kit! In the third corner a car accident has happened, reason why there are first-aid things at the Jail!

Edition: Thailand edition, standard box Ref. 00009/763
Publisher: Hasbro, Pawtucket, USA - 2005
Dimensions of the box: 27.0 x 40.0 x 5.5 cm
                     of the board: 25.4 x 25.4 cm
The game:
This edition is from the collection of Roland Klose - D.

This is Hasbro's first edition in this country, at which it apparently was no longer necessary to show the Parker logo on the box as was use till so far. However, Parker is mentioned yet in the text. It is striking that the red bar, both on the lid as on the game board, looks different from what we are accustomed to. Besides, underneath the bar on the board its only said "Property Trading Game from Parker Brothers", of course in Thai as well, without any mention of a copyright.
The number 763, next to number 00009 for the standard version, is the country number for Thailand.

The game is that standard that ieven t's back is light blue. Mr. Monopoly, from the red bar as well as from the funny illustrations on the cards, does not yet deserve this name, because his bow tie is not red, as is the case in other countries since 2000, but simply colorless. Consequently this means he still is Rich Uncle Pennybags in Thailand.
The innerbox is of soft, white plastic and has 10 holes, to be used by the banker as Banker's tray.
The Chance- and Community Chest cards are richely illustrated.
The banknotes are printed in black on colored paper, in the denominations 100 (black on white) - 500 - 1,000 - 2,000 - 5,000 - 10,000 and 50,000 ฿ (Baht). Also on these banknotes the Parker engine has been replaced by the Thailand train.
The 11 tokens of this edition are: car - wheelbarrow - dog - canon - moneybag - iron - hat - ship - rider-on-rocking-horse - shoe and thimble.
The houses and hotels are of plastic, do have a centric chimney and overhanging roofs.

The properties are not only from Bankok but from other cities and areas in the country as well. 
From Go onwards they are:

จุดเริ่มต้น /Go -  ุมแสง /Chumsaeng - หีบสมบัติ /Community Chest - ปากนํ้ๅโพ /Paknampho - ภาษีรายได้ /Income Tax - สถานีขอนแก่น /Khon Khaen Station - บ้านไผ่ /Ban Phai - บัฅรเสี่ยงโชค /Chance - ท่าพระ /Tha Phra - ภนนศรีจันทร์ /Sri Chan -  อยู่ในคุก/แค่มาเยี่ยม  /In Jail/Just visiting -  ถนนจะนะ /Jana - บริษัทการไฟฟ้า /Electric Company - ถนนเพชรคีรี /Phet Kiri - หาดใหญ่ /Hat Yai -  สถานี สุราษฎร์ธานี /Surat Thani Station -  ไชยา /Chaiya - หีบสมบัติ /Community Chest - เกาะพะงัน /Ko Pha Ngan - เกาะสมุย /Ko Samui - จอดฟรี /Free parking - เกาะล้าน /Ko Lan - บัฅรเสี่ยงโชค /Chance - - ศรีราชา /Sriracha - สถานีเชียงใหม่ /Chang Mai Station - สันกำแพง /San Kampaeng - ท่าแพ /Tha Phae - บริษัท การปรปา /Water Works -ช้างคลาน /Chang Klan - ไปเข้าคุก /Go To Jail - ราไวย์ /Rawai - กะรน /Ka Ron - หีบสมบัติ /Community Chest - ป่าตอง /Pa Tong - สถานีหัวลำโพง /Hua Lumphong Station - บัฅรเสี่ยงโชค /Chance - สุขุมวิท /Sukhumvit - ภาษี มูลค่าเพิ่ม VAT tax and สีลม /Silom.    
The black Parker locomotive has been replaced by the front of the Thai train.

Both dice are, as was to be expected, white with black pips.

Edition: The fortune of Millionaire
Publisher: Inland manufacturer - ±2005
Dimensions of the box: 22.3 x 40.2 cm.  
Het spel:
This issue was discovered in 2011 by Jacqueline Janssen - Alkmaar - NL.
The game board has a yellow playside and a green back. There are 29 numbered propperties, on the board provided with a picture. From them it may perhaps be concluded the properties to be from Bankok (=กรุงเทพมหานคร, pronounce: Krung Thep Maha Nakhon).
The color groups (always 2 per side) are: 1 - 2 and 5 - 6 - 7 <> 8 - 10 - 11 and 13 - 14 - 15<> 16 - 17 - 18 and 20 - 21 - 23 <> 24 - 25 - 26 and 28 - 29. 
There are 4 "station spaces", but they are for sure no stations.
At Go you receive 2000 Baht.

The pictures on the corner spaces of the board are striking:
1. The rascal, a poor imitation of Mr.Monopoly, with a fat head, is clubbed to jail by the police. A red arrow suggests he may leave.
2. On the "Free parking" space is a shadowy snorkeller.
3. On the 3^rde corner is a policeman grabbing the rascal at his feet and dragging him across the board to jail, according to the red arrow.

The cards belonging to this set are light blue with 1 column showing rents for 1 to 4 houses. The back is blank.
There are 74(+2 blank) light blue cards who most probably have to be equally divided as a kind of Chance (the image of a wheel of fortune on the Go corner) and Community Chest cards (a color picture on the Free Parking corner).
The 6 tokens consist of plastic figures and are respectively car - beaker - elephant (white) - rabbit - rabbit and a bear. Note that 4 of the 6 tokens are charms (given the eylets) similar to the official story from Parker Brothers as if Charles B. Darrow would have choosen these tokens, because his wife had a bracelet with such charms.)  

There are 8 white hotels and 24 yellow houses. 
The money consists of one side printed banknotes in 6 denominations of resp. 10 – 50 - 100 - 500 - 1000 en 5000 Baht. 
The image on the notes is always the same.         

The innerbox is divided a simple manner with pink paper into 6 boxes to store the accessories.
The Rules are, like in most cases with games of inland manufacture, printed on the inside of the cover, which is very practical because the can not be lost.
The dice are white and slightly smaller than usual with a big red dot as one, and a red four, the so-called Chinese dice.

It appears from a sticker on the lid of the box that this edition was bought at the Krungdeb co-op in Bankok for the price of Bath 56,-.
