There is no such thing as “the one right way.” It has a wide variety of entry points and a high ceiling. Puzzle Tanks starts with very simple problems, such as the 5 + 6 = 11 task described earlier, but the higher level problems have stumped some very bright, well educated people.
HINGS TO HECK To make sure the batteries in your TI-73 are in good working condition, turn on your TI-73. If there is a low-battery message on the screen, turn the TI-73 off and follow the battery replacement procedure in Appendix C of your TI-73 Guidebook.

Use the arrow keys and the enter key to select the level of play you’d like to start with. To familiarize yourself with the game, you may want to choose the Beginner level first. Once you choose the level you want, a problem will be presented. After you’ve read the problem, press any key to begin solving it.
You will use the main menu bar located at the bottom of the screen to interact with Puzzle Tanks. The five keys directly below the game screen (hereafter referred to as the Master keys) correspond directly to the five items in the menu bar.
OW TO In Puzzle Tanks, you are given the option to choose from four levels of play: Beginner, Expert, Master and Champion. Each level increases in difficulty. The tanks are chosen at random from 1 to 9 units; the goal amount is also chosen at random.

ROGRAM Expert Level In the expert level the problems are more challenging. Suppose you had tanks holding units of 6 and 5, and the goal is 8. There could be a couple of different solutions: You could do 6 - 5 eight times, emptying each of the remaining units into the truck.
The goal was 1, so the problem was solved in five steps. Is there a solution with fewer steps? Champion Level Champion is the most challenging level of play. At this level, you may be pre- sented with a problem that has already been solved by another player who is the champion for that problem.

ROGRAM ESCRIPTION You can scroll through the Champion List using the arrow keys on the calcula- tor. The menu bar in the Champion List screen contains 3 options; PLAY, CLR and CANCL. If you see a game you would like to play, use the arrows to high- light that game and select PLAY from the menu bar.
This error indicates the Flash Installer is unable to communicate with the TI-73. The problem is usually associated with the TI-GRAPH LINK ™ cable and its connection to the TI-73 and/or to the computer. Make sure the cable is firm- ly pushed into the calculator and the computer.
Miscellaneous If you obtain new or upgraded software for your TI-73, you may need to provide your current software version and/or the serial number of your unit. It is also good to know your version number in case you have difficulties with your TI-73 and need to contact technical support.
