La Primitiva
Spain's oldest active lottery, running since 1763 in its modern form. A straightforward 6-from-49 game with two bonus mechanics that shape the top prize.
How it works
The rules in plain language
Pick 6 numbers from 1 to 49. A "complementario" number and a "reintegro" (0-9) are drawn separately. Match all six main numbers for the jackpot; match 5 + complementario for the second tier; match the reintegro alone for a small fixed prize. A "Categoría Especial" adds an extra jackpot tier when you match 6 + reintegro.

Why LottoWise
Smarter play, honest math
LottoWise will not change your jackpot odds — nobody can, they are fixed by the game. Here is what we do differently:
Coverage you can verify
Systematic play plans compute exact coverage guarantees for secondary prize tiers (3, 4, or 5 matches). No black-box picks — you see which combinations you bought and which tier you are locked into.
Fewer prize splits
We flag overplayed patterns (birthdays, sequences, popular dates) in your region. If you do win, you are less likely to share the pot with thousands of others.
Rollover timing
Real-time jackpot and rollover tracking so you enter when expected value per ticket is strongest. Not every week is mathematically equal.
News-correlated signals
Our system reads lottery-related news — jackpot changes, rule updates, operator announcements — and correlates them with draw patterns. No other analytics tool does this.
No "lucky picks". No "guaranteed wins". Just analysis you can verify.
