Match. Beat. Repeat. And learn a new language that way! Koski is a unique multi-language card game for kids and their parents, which uses memorization techniques to enable language learners to get more from their learning experience. Rules of Koski are as simple as that! Match images with their designations in primary and target (learning) languages to form a pair first, along with the final triplet afterwards. Player with more triplets in their shelf wins the game! You only have 60 seconds on your turn to do that before your rival steps in… Phew, good thing is that there are several rounds! Before you start, primary and target (learning) languages are to be selected and then brace yourself for outstanding card-game learning experience! Did someone say... difficult? Decide upon the difficulty level, which suits you best: elementary level to learn new words from scratch, mid level to practice at a moderate pace or nightmare-hard level to master your knowledge. With 5+ languages available, you can learn new words from preferred topical decks in a playful way. Play with your family members and friends in a private room, other random players or even all-mighty bot, which seems to know anything and everything! Beat all your rivals and be the first one on the rating board!

Verdict
The clearest difference is in-app purchases: Koski at none against Lost Bubble's 10. Lost Bubble's advantage is chart position (#146 vs unranked) and iOS requirement (12.0 vs 15.0). On price, ads and device support there is nothing between them.
