# Kluchi vs Einstein Riddle Island Puzzle

The clearest difference is review sentiment: Einstein Riddle Island Puzzle at 100% against Kluchi's 50%. Einstein Riddle Island Puzzle also leads on ratings volume (7 vs 1). Kluchi's advantage is ads (none vs shown) and rating (5.0 vs 4.7). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. Kluchi sells 1 one-off in-app purchase and Einstein Riddle Island Puzzle sells 6 in-app purchases, starting at $0.99 per 7 days. Whichever you choose, the download price is not the number that matters.

Kluchi holds the better App Store score, 5.0 against 4.7. That said, the two scores are not equally well evidenced: Einstein Riddle Island Puzzle has 7 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 50% of Kluchi's written reviews are positive against 100% of Einstein Riddle Island Puzzle's, so the app with the better star average is not the one people write more warmly about.

Kluchi ships an update every 3 weeks, Einstein Riddle Island Puzzle every 4 weeks. The most recent releases landed on September 4, 2026 and August 8, 2026 respectively.
