earn and spend the client logs, with its amount and its source/sink (position).
Amounts are real. Not measured: gold (stat upgrades are not logged), and players' balances. Earned minus spent is the net change in what players hold, not their stock.
The middle bar is the currency; a source is not linked to a particular sink.
Relic tokens and loot currencies grow exponentially with progress, so their amounts are dominated by the most advanced players. Use "number of grants" for those.
Spent can exceed earned (gems: about 2×): players spend what they already held, and an account restored on a new device starts with its old balance but no logged income.
Among October installs, gems spent exceeded gems earned for only 83 of 1,524 gem spenders, so this is not a game-wide missing source.Rows: the action just done. Columns: the next one. Darker = larger share of that row. The END column is the share of sessions that stop after that action. Rows with fewer than 30 steps are greyed.
