** CZ - český popis hned za anglickým ** EN - Train Snake game Train Snake is a classic retro type of game Snake. Where you are trying to collect all the objects on the screen while trying to avoid your own wagons, walls and successfully reach the finish which is an open gate. The gate opens when all the objects are collected. Practice precision, reflexes, combination and logical thinking. There are 50 levels (20 free) in the game. The game is suitable for all ages. After buying the full version it will remove ads and unlock all the levels. You can control the train by using touch gestures. The game is created as a multiplatform using Unity and as inspiration we took the original game Train, which was created in 1993 by Miroslav Nemecek. Train Snake will be further extended with new functions. In the next version we would like to implement online ranking system. You can send any ideas / suggestions / comments to kontakt@mixedapps.cz ** CZ Hra VLAK je klasická retro hra typu had (Snake), ve které se snažíte posbírat všechny předměty na obrazovce a přitom se vyhýbat svým vagónkům a také zdím a zdárně dojet do cíle, kterým je otevřená brána. Brána se otevře, jakmile jsou všechny předměty posbírány. Procvičuje přesnost, postřeh, kombinační a logické myšlení. Ve hře je 50 scén (20 zdarma). Hra je vhodná pro všechny věkové kategorie. Po zakoupení plné verze dojde k odstranění reklamy a odemčení všech scén. Vlak se ovládá pomocí dotykových gest, kdy nejdříve v dané scéně je potřeba si vybrat kam by se měl vlak rozjet. Vybírat si můžete ze 4 směrů (nahoru, dolů, doleva a doprava). Jakmile se vlak rozjede, tak pak už se mašinka otáčí jen doleva nebo doprava podle toho, zda kliknete do levé nebo pravé poloviny obrazovky. Hra je vytvořena jako multiplatformní pomocí Unity a jako inspiraci jsme si vzali původní hru Vlak, která byla v roce 1993 vytvořena Miroslavem Němečkem. Aplikace bude dále rozšiřována o nové funkce. V další verzi bychom rádi doplnili online žebříček. Velice uvítáme jakékoliv nápady / návrhy / připomínky, které prosím posílejte na kontakt@mixedapps.cz

Verdict
The clearest difference is rating: Train Snake at 5.0 against Atoms HD's 3.6. Train Snake also leads on update cadence (weekly vs every 64 months) and iOS requirement (7.0 vs 12.0). Atoms HD's advantage is review sentiment (54% vs 33%) and ratings volume (19 vs 1). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Atoms HD sells 7 one-off in-app purchases and Train Snake sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
Train Snake holds the better App Store score, 5.0 against 3.6. That said, the two scores are not equally well evidenced: Atoms HD has 19 ratings behind it against 1, so its average is the more settled of the two. Written reviews complicate that: 54% of Atoms HD's written reviews are positive against 33% of Train Snake's, so the app with the better star average is not the one people write more warmly about.
Atoms HD ships an update every 64 months, Train Snake weekly. The most recent releases landed on October 16, 2026 and October 14, 2026 respectively.
