Each shape represents a (unique) positive whole number. The sum total of the shapes in each row or column is displayed at the end of each row or column. Use this knowledge to deduce the numerical value of each shape. To set the value for a shape, 1st click on the digit in the 10-key keypad on the left. Then click on one of the four shapes, just to the right (not on the 4x4 grid). *** New: ** Choosing puzzle # is "circular" (Prev. takes you from #1 to #15. Next takes you from 15 to #1). Also, puzzle #15 is a random puzzle. When on #15, clicking "New 15" generates a new random puzzle. Solving tips: Try not to guess. Try to use algebra. Treat the rows and columns as a set of "simultaneous equations".
[New 15] puzzles are generated using a slightly changed algorithm to @grandpasp's original, wherein it can now no longer generate a puzzle with more than one Row containing each of the 4 different Symbols. This will significantly reduce the chance of it generating puzzles with lots of different solutions! The code I originally suggested to @grandpasp which he included to prevent triples & quads in columns as well as rows, has also been restored to what I originally planned, where it no longer allows any triples in columns, whereas @grandpasp's current version does allow for the occasional triple, but I found they were happening too frequently. Code change for that was trivial just changed the test for length of (Shape Rows) > 1 to > 0! The changes were designed to prevent the creation of puzzles with a mega amount of solutions, such as the one shown in the project Thumbnail. To try it ... 1) Click the Flag, 2) Click (Prev), 3) See Inside, 4) Go to the bottom of the [New 15] code, 5) click the "Load Mega solutions puzzle" block & 6) click (Reset). It was generated by the [New 15] code in the project this one's a remix of. The reason there are so many solutions is there are too many lines with one of each Symbol in them. It is easy to deduce that the square must be 4 more than the triangle. All such square-triangle pairs from 4-0 to 9-5 produce multiple solutions each. Values for the Circle & Star can be any pair of digits that add to 15 - (square + triangle) & they can be interchanged with each other!
