📥 Game Collection Backlog Tracker

Add your games and mark which ones you've actually played to see your backlog — games you own but haven't gotten to the table yet.

One percentage, from two counts

Every row is a game and the tick means you have played it. The tracker counts the unticked rows against the total:

backlog % = unplayed games / games owned × 100

The four sample games start at two unplayed, so 2 / 4 = 50.0%. Tick Gloomhaven and it drops to 25.0%, because with four games each one is worth 25 percentage points. That sensitivity fades fast: at 20 games a single play moves the figure by 5 points, and at 100 games by one.

Using it on a real shelf

Add a row per game, not per box. Expansions ride with the base game unless you genuinely think of them as separate purchases; counting them apart inflates both the total and the backlog.
The tick is all or nothing. A game played once and shelved counts the same as one played fifty times, so the number tells you what has reached the table, not what has earned its place.
The card lists every game with its status above the summary row, which makes it usable as a pick-something-tonight shortlist.
The badge rounds to whole percent while the row keeps one decimal, so 1 unplayed out of 6 shows as 16.7% and 17%.

Nothing is stored between visits. For a shelf you want to keep, put the list in a spreadsheet and use this to do the arithmetic when you review it.

Frequently asked questions

What is a board game backlog?

The games you own that have never been played - the shelf of shame. It grows from sales and Kickstarter waves rather than from buying badly, which is why it is worth measuring as a share rather than a count.

How do I get my backlog down?

Play one unplayed game per session instead of a favourite. A 20-game shelf with 8 unplayed sits at 40%; two nights of that rule takes it to 30%, and the games that stay unplayed after a few rounds are the ones to sell.

Does a game I have played once count as played?

Here, yes - the checkbox is binary. If you want to know which games are actually earning their shelf space, the cost per play calculator divides the price by the sessions instead.
