Verdict
The clearest difference is in-app purchases: Impossible Charge at none against The Impossible Letter Game's 4. Impossible Charge also leads on update cadence (every 5 weeks vs every 4 months) and iOS requirement (15.0 vs 17.1). The Impossible Letter Game's advantage is rating (4.6 vs 4.2) and ratings volume (17K vs 25). On price, ads and device support there is nothing between them.
