For the eighth time, after needing to check out my own purchase history, I downloaded Sumbo, but a funny little thing happened this time: it finally advanced to the game itself! (The first seven times, it displayed the message "Zheng Games" which I believe is the company that made Sumbo in
January, but always returned to the application home page.)
But this time, it showed a new word: loading, and then lo and behold, the Sumbo game was finally in business after 36 days of trying! And yes, it works exactly as it's supposed to be: the 16-squared game board shows random numbers from 1 to 9, and they ask you to add up numbers in a columb, row, or diagonal that equal a designated number (such as 15 using 7 and 8), and the correct combinations will change into 0's. And you can use the 0 to add up more combinations, and points are scored for correct totals (usually 20) but 10 points are taken for wrong answers. It's almost like the score boards they used on the long-forgotten 60's-70's version of the original Jeopardy show (before Alex Trebek would host it himself), and the sound effects remind me of it, too! I rate Sumbo four stars--the fifth was perhaps, due to the longer-than-expected wait--but it's still a penniless purchase!
Alas, it also has a 100-second time llmit, and when you cannot do any more combinations, you can change puzzles and score more points until the clock descends to zero.
