Twin Diamonds Review
Twin Diamonds is a diamond-themed three-reel classic from Retro Gaming. Sparkling gems fill the reels, and the top prize waits behind the optional Retro Xtreme bet.
Three reels, five lines
Five fixed lines cover the three rows and both diagonals. Three of a kind pay from 20× the line bet for the lowest symbol, 40× for the next four, then 120×, 150× and 300× for the top symbol. Line bets run from 0.02 to 100.
A Christmas edition, Twin Diamonds Xmas, uses the same rules.

The demo reports a 95% RTP and caps wins at 5,000× the bet. Retro Gaming has many 777 games with these rules; they differ in theme and artwork.
