We typically run out the last rounds of the game, once holdings have settled out, either via spreadsheet or paper. Running all the money by spreadsheet (no monopoly money or poker chips) can easily take an hour or more off the playtime.

friends of mine just started using a spreadsheet to help with this game. They reckon it knocks about 25% of the total playing time for them...

I bought a few $1 calculators specifically to help with my Addition Deficiency Disorder.

I downloaded a spreadsheet a year or 2 ago that we use when we play. Not only does it keep track of everyone's discounts, it also automates the AST, keeps track of population and cities and turn order and calamities, as well as gives player summaries at the end of the game. I can't imagine playing without it, now.

Having a spreadsheet that everyone fills out with purchases has helped us with some strategy. Namely: the guy in the lead by AST or on the board may not be in the lead by points (what really matters).

This was the first game I thought of.

Please upload it!!!!

BGG already has a spreadsheet file that you can download and use for Lost Cities. I've downloaded it and used it for the past month. It is really well done.
