Your card game
Select the game type, then the number of pairs or boards.
12 cards: each drawing appears exactly twice (check passed). Remember to print the card back design too.
How to use it
- Choose "Memory" (matching pairs) or "Picture Lotto" (boards and draw cards).
- Set the number of pairs, or the number of boards and their size (6 or 9 spaces).
- Keep or change the seed, print on heavy paper or cardstock, then cut along the dotted lines.
- For Memory, print the back pattern too: flip the paper along the long edge to align properly.
A worked example
Example: a 6-pair Memory game creates 12 cards arranged in three rows of four: each drawing (star, heart, moon...) appears exactly twice, shuffled using the seed.
A lotto set with 4 boards of 9 images selects 9 illustrations out of 16 for each board; all four boards are completely distinct, and the 16 draw cards cover all illustrations.
Method, underlying assumptions, and limits
Method. Illustrations are chosen randomly using the seed. In Memory mode, each picture is duplicated once and the deck is shuffled; the program verifies that each picture appears exactly twice. In Lotto mode, every board receives 6 or 9 distinct images, and no two boards ever share the exact same combination.
Limits. Two boards may overlap in many pictures: the lotto remains playable, but games are shorter when using fewer boards. Drawings are simple for easy recognition by young children; supervise toddlers under age 3 around small cut-out cards. Set print scaling to 100% to keep cards around 2 inches (5 cm) wide.
Frequently asked questions
What kind of paper should I use?
Heavy paper (around 110 lb / 160 gsm) or thin cardstock glued to the back so pictures don't show through.
Why print the back design?
So all the cards look identical when face down. Flip the sheet along its long edge when printing double-sided.
Are all the lotto boards different?
Yes: no set of images is ever repeated from one board to another, checked before displaying.
Are my settings saved?
No, everything is calculated within the web page and nothing is saved.
