Outnumbered XL is an addictive puzzle game that combines strategy, multiplication skills, and the luck of the draw. Don't know the strategy? Use the Hint button to get you started! Don't have multiplication skills? Don't worry! You will after playing this game for a minute! Don't have any luck? Sorry! Can't help you with that... Outnumbered XL now features four board sizes: Small, Medium, Large, and the new XL board size! It takes around a minute to play a Small game, around 10 for an XL game. Each level is an enlargement of the previous, and they are all fun to play over and over again, no matter what your skill level is. The game-play is based on the decomposition of numbers into their prime factors. This means that the deck is mostly 2's and 3's, some 5's and 7's, and occasional 11's, 13's, 17's, 19's etc... Ex. To take "38", you would need a 2 and a 19. Cards all score their face value, so while the larger cards may be harder to play, that is where you will score the most points. But don't hold on to that 61 for too long! Understand when to Swap. It is all part of the fine risk/reward balance of Outnumbered XL!

Verdict
The clearest difference is in-app purchases: Outnumbered XL at none against Chess's 2. Outnumbered XL also leads on ads (none vs shown) and ratings volume (5 vs 1). Chess's advantage is update cadence (every 3 weeks vs every 5 months). On price, rating and device support there is nothing between them.
