Minesweeper Games (RISC OS)
This is a collection of minesweeper games for RISC OS (1987). RISC OS was an operating system used by Acorn Computers (UK) on their products from 1987-1998 before they sold it to Pace Micro Technology. It was then licenced to RISCOS Ltd which released versions of RISC OS 4 (starting in 1999) and RISC OS 6 (starting in 2007). Castle Technology managed to buy the OS and seperately developed RISC OS 5 for their Iyonix computer, which sold in the UK from 2002-2008. RISC OS 5 is also used on the ARMini computer (2011) released by R-Comp Interactive.
RISC OS expects you to have a mouse with 3 buttons - Left is 'Select', Right is 'Adjust' and the middle button 'Menu' is used to open menus. One interesting feature of all RISC OS minesweeper games is that the timer starts from 0, unlike the Windows version which jumps to 1 on the first click.
Two minesweeper versions for RISC OS deserve special mention: Mine Hunt, by Paul LeBeau, came bundled with OS 3.5 to 3.71 (1994-1998) while Flag Day, by Richard Hallas, comes with all OS 4 (except 4.02), 5 and 6 releases.

|Download: Flag Day 4.02 2001-08-28 |
|Four difficulty levels with 20% mine density, ranging from 8x8 to 27x27. Custom allows up to 99x99. Highscore list saves best 5 scores for each level (as of version 5.00). You can create skins and graphics for the game (as of version 4.00) or choose from skins that come with the game. Hint feature flags or opens an unknown square, but is can only be used once per 50 mines on a level. You can use standard mouse control or the original Search & Flag modes (where you alternate between 'Search' mode, with a magnifying glass cursor to open squares, and 'Flag' mode, with a flag cursor to flag mines). There are many options such as making corners or edges always safe, making squares larger, using 'uncertainty markers', showing mines at the end of the game, or using sound effects.|
NOTES: First public release was 2.54 (1992-08-06) and game was sold by RISC User magazine for several years. Since 2002 the game is supplied free with RISC OS 4, 5 and 6 releases. Current version is 5.05. More details available in main article.

|Game has 5 difficulty levels and allows custom games up to 64x64 (limited by your screen resolution). Levels are Beginner (8x8, 10 mines), Better (16x8, 20 mines), Intermediate (16x16, 40 mines), Good (24x16, 60 mines) and Expert (30x16, 99 mines). Highscore list saves best 5 scores for each level. You place flags and questionmarks in the standard way, but to chord you left click ('select') and press the Shift key. If you click a mine the game ends and the exploded mine is highlighted in red, while correctly marked mines are highlighted green. Instead of a Smiley Face, you click on a Man to start new games (which becomes a Skull if you lost). You can change the colour of the Timer and Mine counter by clicking on them. It is possible to lose on the 1st click, and you must flag all mines to win. Sound effects include funny messages when you lose. First public release was 1.04.|
NOTE 1: Game came bundled with RISC OS 3.5 to 3.711. First public release was 1.04.
NOTE 2: There is a Cheat, announced by LeBeau on 19 Mar 1998 in comp.sys.acorn.games: "If you want to impress your friends with your MineHunt prowess, hold down Ctrl when you click on the 'man' to start a new game. Then keep Ctrl held down while you clear the board with a frenzy of seemingly random clicks."
1. According to New Features of RISC OS 3 Version 3.5 written on 1994-04-18, the OS having been released two days earlier. After 3.71 the OS was sold to RISCOS Ltd who released OS 4.02 in July 1999 without Mine Hunt, then replaced it with Flag Day.
 1993 - MineHunt
|Michael Ellis (England)|
|Standard 3 levels and Custom but also includes 'Impossible', which is Expert but with 160 mines. You chord with both buttons as usual, but if a number that already touches the correct number of flags is opened, the game automatically chords on it too. You need to flag all mines.|
NOTE 1: The "Auto Click" chording method was first used earlier in 1993 by GMines for the Atari computer. It is unclear if Ellis invented the idea seperately.
NOTE 2: Ellis states he was only aware of 2 minesweeper games for RISC OS, both called Mine (one by Liger Software, the other by Walters & Fawcett) when he wrote his game. A few months later a different minesweeper game Mine Hunt, which had been circulating since 1992, was released with RISC OS 3.50.
 1993 - Mine Sweeper
|S. J. Williams|
|Download: Mine Sweeper|
|There are 60 mines hidden in a 20x20 grid. Your job is to flag the mines. When you think you have found all of the mines, click the "Reveal" button to see if you have won. There is no timer or Highscore list. Flagging a square turns it yellow, mines are simply the letter "M" and there is no chording. There is a small explosion sound effect when you lose.|
NOTE: Filename is Sweeper, but Helpfile calls it MineSweeper and game window calls it Mine Sweeper.
 1994 - Minesweeper
|Stefan Bellon (Germany)|
|Download: Minesweeper 1.20 1997-11-04|
|There are 2 modes each with 5 grid sizes, and each size has 10 density levels. In Minesweeper mode you find and flag all the mines. In Mission mode you start at the top left corner, and must collect men before nagivating to the bottom right corner. Mission mode only allows you to move ("walk") to adjacent squares, flags are optional, and there are brick walls you must circumvent. Both modes let you save a game and load it later. Highscore list saves best 3 times for all 100 levels.|
NOTE 1: Mission mode is essentially a clone of Relentless Logic with a few extra features. Game is also known as Minesweep due to its filename.
NOTE 2: The game will work on Iyonix according to Bellon if you make some changes:
1) Delete all lines in the !Run file that refer to the sound modules EXPLOSION and WellDone
2) Find the two occurrances of EXPLOSION and WellDone in !RunImage and replace the string EXPLOSION and WellDone with the strings 9 and 1 respectively.
