Who we are and how the numbers work
About Per Diem
Per Diem (perdiemsweeps.com) is an independent, no-purchase map of US sweepstakes casino daily bonuses. We do not sell coins, take deposits, or run a casino. We track free Sweeps Coin claims, the games that keep the least, and each site's cash-out floor — then give you a daily checklist so streaks do not break.

How “free money / month” is calculated
- Start from the site's no-purchase weekly Sweeps Coins at a perfect streak (published daily + ladder, not purchase or VIP gifts).
- Subtract a 0.5% blackjack house cut for each required bet (playthrough). A 1x site keeps about 0.5% of the weekly coins; a 3x site keeps about 1.5%.
- Convert to a month: weekly remainder × 52 ÷ 12.
- Price Sweeps Coins at $1 each — the usual prize redemption rate.
We do not count purchased packages, VIP dailies that require spending, mail-in entries, or “up to” welcome banners. Those inflate every other list. A bad card run can still wipe a week even when you play the chart. The current 7 best sites total about $189/month under this formula.
What we recommend playing
Blackjack (or the closest published high-return table game) using basic strategy. Slots typically keep ~5¢ per $1 bet. We never recommend slots for clearing free coins. Each casino page names the exact game and, where we have it, a strategy card.
Independence and affiliate links
Some “Earn now” buttons use referral links. That does not change the ranking: sites are ordered by the formula above, not by who pays us. Numbers that change are logged on the changelog with a date. If a figure is wrong, the dated log is the correction trail.
