Spel Bound
Read full descriptionHide full description
Have fun rolling balls around trying to put them in the holes while learning the alphabet and how to spell various animal names. There are thirty-five animals to choose from. Zoom in to get a closer look to make your choice. Tip the device up/down, right/left to move the balls around. As the ball drops in the hole the name of the letter is pronounced. Be careful, if you tip the device too far the balls will fall out. Once all the ball are in place the word is verbally spelled out as each ball enlarges followed by the name of the animal. When finished the animal makes their sound. Two animals don't make a sound and deliver a special treat. Tap on the "info" icon to find out more about the animal. Return to Spel Bound to choose the same or a different animal.

Verdict
The clearest difference is in-app purchases: Spel Bound at none against Sandbox Planet's 6. Spel Bound also leads on ads (none vs shown). Sandbox Planet's advantage is update cadence (every 3 months vs every 28 months). On price, device support and iOS requirement there is nothing between them.
