Optimal Backpack turns the 0/1 knapsack problem every computer science student knows into a fun hiking adventure. Players pick a tent, compass, thermos, camera and dozens of other gear pieces, each with its own weight and value, and try to fill the pack to the highest value without passing the weight limit. The best value of every pack is computed with dynamic programming and shown as the target, so every pack can truly be beaten. Thirty packs on six mountains show players that grabbing the best value-per-kilo first (greedy) often fails, and the DP Table mode shows step by step how that table is filled. A record for each pack, a daily pack with a streak and a gear collection give players a reason to come back. The game is easy to re-skin with the mascot, colours and items of the ordering campus, tutoring centre or outdoor gear brand. Try it right here below, then picture a game like this featuring your brand’s logo, characters and prizes.
